[PATCH 5/8] foll-vfork.exp: Use with_test_prefix.


Looking at a FAIL in this test (caused by some other changes I was
working on), I had some trouble matching the gdb.sum output with the
test's code.  The gdb.sum output currently looks like:

 PASS: gdb.base/foll-vfork.exp: set verbose
 PASS: gdb.base/foll-vfork.exp: insert first vfork catchpoint
 PASS: gdb.base/foll-vfork.exp: continue to first vfork catchpoint
 PASS: gdb.base/foll-vfork.exp: set follow-fork parent, vfork through step
 PASS: gdb.base/foll-vfork.exp: vfork parent follow, through step
 PASS: gdb.base/foll-vfork.exp: set follow-fork parent, vfork to bp
 PASS: gdb.base/foll-vfork.exp: break, vfork to bp
 PASS: gdb.base/foll-vfork.exp: vfork parent follow, to bp
 PASS: gdb.base/foll-vfork.exp: set follow-fork child, vfork and exec to main bp
 PASS: gdb.base/foll-vfork.exp: vfork and exec child follow, to main bp
 PASS: gdb.base/foll-vfork.exp: set follow-fork child, vfork and exec through step
 PASS: gdb.base/foll-vfork.exp: vfork and exec child follow, through step
 PASS: gdb.base/foll-vfork.exp: set follow-fork parent, tcatch vfork
 PASS: gdb.base/foll-vfork.exp: vfork parent follow, set tcatch vfork
 PASS: gdb.base/foll-vfork.exp: vfork parent follow, tcatch vfork
 PASS: gdb.base/foll-vfork.exp: vfork parent follow, finish after tcatch vfork
 PASS: gdb.base/foll-vfork.exp: set follow-fork child, tcatch vfork
 PASS: gdb.base/foll-vfork.exp: vfork child follow, set tcatch vfork
 PASS: gdb.base/foll-vfork.exp: vfork child follow, tcatch vfork
 PASS: gdb.base/foll-vfork.exp: vfork child follow, finish after tcatch vfork (followed exec)

This patch changes the tests to use with_test_prefix instead of
hardcoding a prefix in gdb_test/gdb_test_multiple (and being
inconsistent).  We now get:

 PASS: gdb.base/foll-vfork.exp: set verbose
 PASS: gdb.base/foll-vfork.exp: insert first vfork catchpoint
 PASS: gdb.base/foll-vfork.exp: continue to first vfork catchpoint
 PASS: gdb.base/foll-vfork.exp: vfork parent follow, through step: set follow-fork parent
 PASS: gdb.base/foll-vfork.exp: vfork parent follow, through step: step
 PASS: gdb.base/foll-vfork.exp: vfork parent follow, to bp: set follow-fork parent
 PASS: gdb.base/foll-vfork.exp: vfork parent follow, to bp: break, vfork to bp
 PASS: gdb.base/foll-vfork.exp: vfork parent follow, to bp: continue to bp
 PASS: gdb.base/foll-vfork.exp: vfork and exec child follow, to main bp: set follow-fork child
 PASS: gdb.base/foll-vfork.exp: vfork and exec child follow, to main bp: continue to bp
 PASS: gdb.base/foll-vfork.exp: vfork and exec child follow, through step: set follow-fork child
 PASS: gdb.base/foll-vfork.exp: vfork and exec child follow, through step: step over vfork
 PASS: gdb.base/foll-vfork.exp: vfork parent follow, finish after tcatch vfork: set follow-fork parent
 PASS: gdb.base/foll-vfork.exp: vfork parent follow, finish after tcatch vfork: tcatch vfork
 PASS: gdb.base/foll-vfork.exp: vfork parent follow, finish after tcatch vfork: continue to vfork
 PASS: gdb.base/foll-vfork.exp: vfork parent follow, finish after tcatch vfork: finish
 PASS: gdb.base/foll-vfork.exp: vfork child follow, finish after tcatch vfork: set follow-fork child
 PASS: gdb.base/foll-vfork.exp: vfork child follow, finish after tcatch vfork: tcatch vfork
 PASS: gdb.base/foll-vfork.exp: vfork child follow, finish after tcatch vfork: continue to vfork
 PASS: gdb.base/foll-vfork.exp: vfork child follow, finish after tcatch vfork: finish (followed exec)

Split off to a separate patch because this is the first change in the
series that actually changes gdb.sum output.
