d: Don't run all permutations for fail_compilation tests.

Fail compilation tests only check for language errors from the front-end, all
default option switches do nothing to alter the error.

gcc/testsuite/ChangeLog:

	* lib/gdc-utils.exp (gdc-convert-test): Clear PERMUTE_ARGS for
	fail_compilation tests if not set by test file.
