[v3,00/10] A couple of CI improvements

Message

Hi,

this patch series addresses a couple of issues I've found while
investigating flaky CI jobs. Besides two more fixes for flaky jobs it
also removes some stale code and simplifies the setup on GitHub Actions
to always use containerized jobs on Linux.

Test runs can be found for GitLab [1] and GitHub [2].

Changes in v2:

  - Expand a bit on the reasoning behind the conversion to use
    containerized jobs.
  - Fix commit message typo.
  - Properly fix the race in t7422 via pipe stuffing, as proposed by
    Peff.
  - Link to v1: https://lore.kernel.org/r/[e-mail]

Changes in v3:

  - Another iteration on the SIGPIPE test, which should now finally plug
    the race.
  - Link to v2: https://lore.kernel.org/r/[e-mail]

Thanks!

Patrick
