[LibFuzzer] Fix fuzzer-oom.test on OSX.

On OSX (and other platforms) the `__sanitizer_print_memory_profile()`
sanitizer runtime function is not available so print out the text
`Live Heap Allocations:` to keep the ``fuzzer-oom.test`` happy.

In the future if we want to better test information about the live
heap allocations we will should split that out into a separate test
that can be disabled depending on the host platform.
