Retry flaky compile_invalid_pyc_invalidation_mode test (#4043)

Retry the flaky `compile_invalid_pyc_invalidation_mode` if it fails. I
don't understand why this happening in the first place (we have code
that should catch those cases, but also those cases shouldn't be
happening at all) and this is terrible hack, but it fixes the test
flakes.

Fixes #2672
