[gdb/testsuite] Disable inferior output in gdb.base/foll-vfork.exp

Test-case gdb.base/foll-vfork.exp has inferior output that is not needed, but
which makes the regexp matching more difficult (see commit 1f28b70def1
"[gdb/testsuite] Fix regexp in gdb.base/foll-vfork.exp").

Disable the inferior output using '#if DEBUG'.

Tested on x86_64-linux.
