Test runners on debug kernels occasionally fail with:

# # RUN tls_err.13_aes_gcm.poll_partial_rec_async ... # # tls.c:1883:poll_partial_rec_async:Expected poll(&pfd, 1, 5) (0) == 1 (1) # # tls.c:1870:poll_partial_rec_async:Expected status (256) == 0 (0) # # poll_partial_rec_async: Test failed at step #17 # # FAIL tls_err.13_aes_gcm.poll_partial_rec_async # not ok 699 tls_err.13_aes_gcm.poll_partial_rec_async # # FAILED: 698 / 699 tests passed.

This points to the second poll() in the test which is expected to wait for the sender to send the rest of the data. Apparently under some conditions that doesn't happen within 5ms, bump the timeout to 20ms.
