[Fuzzer] Test failure on Linux x86-64

Continuing my quixotic effort to get 'check-all' clean, I am seeing a
Fuzzer failure on x86-64 Linux. Do any builders run fuzzer tests?

FAIL: libFuzzer :: value-profile-mem.test (103 of 103)

FWIW I think that one was always flaky.

Then it seems like the test should be marked UNSUPPORTED, on Linux if
not other systems. Who can make a ruling on that?

I haven’t seen this test being flaky on our bots.
@Matt Morehouse, have you?
