Remove HP-UX reference in foll-vfork.exp
FAIL: gdb.base/foll-vfork.exp: exec: vfork parent follow, finish after tcatch vfork: continue to vfork

FAIL: gdb.base/foll-vfork.exp: exit: vfork child follow, finish after tcatch vfork: continue to vfork
It happens for plain gdb.base/foll-vfork.exp runtest on Fedora 23 x86_64.

So I have reverted it and just simplified the comment.
The third case is not necessary during testing but I have changed back all the
3 cases.
Pedro Alves:
I know it was that way before, but would you mind moving this to a helper
proc.
