tests/avocado/replay_kernel: Mark the test_x86_64_pc as flaky

It's failing very often, so don't run this by default anymore
until it gets fixed.

We should replace all of the "skip if GITLAB_CI" checks
with "skip on QEMU_TEST_FLAKY_TESTS" (or other check as
appropriate), I think.

Hmm I suspect https://gitlab.com/qemu-project/qemu/-/issues/1961 which
has a fix ready:

I just gave it a try, too, and it does not fix the issue for me.

Is this test still working for anybody?

Yes ... the question is whether they just time out because gitlab is too 
slow (in that case we should increase the timeout), or whether they are 
really flaky ... needs some time for investigation, I guess.
