testsuite, jit, Darwin: Add libSystem to a test.

test-ggc-bugfix.c fails early on Darwin versions using a linker that
complains if libSystem is not present on user-land link lines.

Add this to fix that specific issue.

gcc/testsuite/ChangeLog:

	* jit.dg/test-ggc-bugfix.c: Add libSystem for Darwin.
