fix(main): accept the large-file test's disk-space skip, retry timed-wait latency

Run 41245658018 (b9bf246ea2). linux: agc_shader_disk_cache_large_file skips
when the runner has under 3 GiB free and check_skips.py did not list that
reason. windows: guest_timed_wait_cpu aborted on a runner scheduling hiccup
(latency bound exceeded, #13710 made it serial but it is still timing-based).
