libphobos, testsuite: Add prune clauses for two Darwin cases.

Depending on the permutation of CPU, OS version and shared/non-
shared library inclusion, we get can get two warnings from the
external tools (ld64, dsymutil) which are not actually GCC issues
but relate to the external tools.  These are alrrady pruned in
the main testsuite, this adds them to the library.
