[LibFuzzer] Fix flakey ``fuzzer-trace-pc.test`` test on OSX

When running `LLVMFuzzer-FullCoverageSetTest-TracePC` the memory limit
is sometimes hit which lead to the test failure.

I'm guessing that much more memory is needed on OSX than Linux because
it takes many more iterations for LibFuzzer to hit BINGO on OSX for this
test. I'm not sure if this is to be expected but given that this test
is relying on program counter values it seems reasonable to expect that
the behaviour between platforms could differ.
