Enhance github action for uftrace

[kangtegong]

uftrace used travis CI until recently, but currently github action is added.

Newly-added github action workflow still need some improvement including pre-commit, coverity scan, etc. I think it would be great if someone set these things up.

I've added pre-commit support for PR test in 836bc556f9 as it's kind of urgent. I think we can add coverity scan support for nightly build/check as it only allows a limited (2?) runs in a day IIRC.

Thank you :) If this issue is urgent, shall I add coverity scan for github action? Or are you going to add coverity scan soon?

[namhyung]

The coverity scan is not urgent, it's just nice to have. :)
