CI: fix test failures in container

Following tests were failing:

- test_Config.cpp
    - Testing writing to read-only file fails when run as root because
      DAC is overridden -> fixed by adding normal user and running the
      tests under it
- test_Sound.cpp
    - Test tries to play sound so `pipewire` is required, which in turn
      requires D-Bus so run the tests through `dbus-run-session`

Fixes #765
