Force test_rng_state to run with fake tensor prop (#89641)
I'm not really sure what desertfire's intended follow up was
on https://github.com/pytorch/pytorch/pull/87490 because when I remove
the unsupported() call, dynamo tests pass. But the change here is
conservative and I think strictly better than the current situation.
The idea is to force fake tensor pop on for the test, and then just
observe that we are doing a graph break. Clearly, export doesn't work,
so I manually xfail it.
