testsuite: Fix unstable duplicate test names in pr111527.exp [PR111527]

pr111527.exp does not call runtest_file_p, so with parallel make
check more than one runtest instance can run it and the number of
duplicate test names varies from run to run.  Take the
gcc_parallel_test_run_p lock like linkage.exp does so the tests
run only once.

gcc/testsuite/ChangeLog:

	PR driver/111527
	* gcc.misc-tests/pr111527.exp: Serialize with
	gcc_parallel_test_run_p to avoid duplicate test names.
