CI: Travis tests are not running

This was a silent failure for 12 days. I guess this means that it's time to move to Github Actions completely. Most of the work is already redundant, the two outstanding things I can think of are as follows:

• Python tox tests. This should be moved to Github Actions immediately.
• ARM builds, this needs to stay of Travis until Github supports ARM runners. Hopefully with MacOS M1, maybe they'll have something like that soon. Based on this comment: Support for VMs on Apple M1 actions/runner-images#2187 (comment), it will probably take some time.

For the arm builds, it would probably be best to add a cross compilation job for now, that is what I'm working towards in svt-av1

Good idea. Really the only reason we have this is to avoid cross-platform breakage.

#775 merged, tox tests are now running on Github actions. There is still an issue with the MacOS tox tests, and it seems to have something to do with Python version.
