Initial GitHub Actions workflow.

[jezdez]

Travis CI has a new pricing model which places limits on open source.

Many projects are moving to GitHub Actions instead, including Jazzband projects:

• https://github.com/orgs/jazzband/projects/1
• Should we disable travis? help#206

This is based on jazzband/contextlib2#26.

This contains a work-around for #266 until there is a real fix, e.g. via #271 etc.

No more mention of Travis CI in the codebase:

$ git grep -i travis
$

So I deleted it:
