tests/extmod/select_poll_eintr: Skip unreliable test in Github CI.

AJMansfield · AJMansfield · commit 26d9bf2ff743 · 2025-07-22T14:52:55.000-04:00
extmod/select_poll_eintr.py is a constant source of spurious failures in
Github CI. This PR adds it to the list of tests skipped in that
environment in order to improve the test suite's false positive rate and
positive predictive value in detecting defects.
