[LibFuzzer] Disable the `fuzzer-trace-pc.test` test on non-linux platforms.

On OSX this test sometimes fails due to the
`LLVMFuzzer-FullCoverageSetTest-TracePC` program going over the
default 2GiB memory limit. This shouldn't be happening and needs
investigating. For now just disable the test so we can set up an
OSX buildbot.
