    tests: Use TapTestRunner in functional tests if available
    
    We want to unify test outputs into a format that we can convert to
    JUnit. As the GLib tests already output TAP, and meson converts TAP
    to JUnit, add optional support so our functional tests also output
    TAP.
    
    This is meant to be enabled in CI.
