[llvm-ar][test] Add tests failing on Darwin

These tests that failed on Darwin but passed on other machines due to the default archive format differing
on a Darwin machine, and what looks to be bugs in the output of this format.
I can not investigate these issue further so the tests are considered expected failures on Darwin.
