81779658 - [Fuzzer][Test-Only][Darwin] Mark coverage.test and exit_on_src_pos.test unsupported (#165408)

[Fuzzer][Test-Only][Darwin] Mark coverage.test and exit_on_src_pos.test unsupported (#165408) These tests are currently failing on some CI macOS instances due to an issue with the system symbolizer. This patch marks the tests unsupported on Darwin while we wait for all CI machines to be updated to a newer OS. rdar://160410051
