[gdb/testsuite] Use with_cwd in gdb.src/pre-commit.exp

I ran the testsuite and ran into ERRORs in two test-cases,
gdb.trace/save-trace.exp and gdb.threads/tls-sepdebug.exp.

Recently added test-case gdb.src/pre-commit.exp changes the working directory,
and the change stays active in following test-cases, which was not the
intention.

Fix this using with_cwd.

Tested on x86_64-linux.
