[commit] a bit of cleanup in a couple of gdb.multi/ tests

[Pedro Alves <pedro at codesourcery dot com>]

I was diffing test results in two different build trees, and noticed:

 -PASS: gdb.multi/base.exp: file /home/pedro/gdb/baseline/build/gdb/testsuite/gdb.multi/hangout
 -PASS: gdb.multi/base.exp: add-inferior -exec /home/pedro/gdb/baseline/build/gdb/testsuite/gdb.multi/goodbye
 +PASS: gdb.multi/base.exp: file /home/pedro/gdb/dan/build/gdb/testsuite/gdb.multi/hangout
 +PASS: gdb.multi/base.exp: add-inferior -exec /home/pedro/gdb/dan/build/gdb/testsuite/gdb.multi/goodbye

 -PASS: gdb.multi/bkpt-multi-exec.exp: add-inferior -exec /home/pedro/gdb/baseline/build/gdb/testsuite/gdb.multi/crashme
 +PASS: gdb.multi/bkpt-multi-exec.exp: add-inferior -exec /home/pedro/gdb/dan/build/gdb/testsuite/gdb.multi/crashme

There's no need to leak the full paths.  While I was there, I noticed
not all tests had distinct messages.

All fixed with this patch.  I've applied it.

	* gdb.multi/base.exp, gdb.multi/bkpt-multi-exec.exp: Use
	clean_restart, make sure every test has a distinct message, and
	that messages don't include the executable' full path.
