Use ruff instead of flake8. Aside from being substantially faster, ruff
includes a lot of flake's plug-ins built-in, some of which may be useful
to enable as a follow-up.

Put the argument at the right place.

Alpine 3.19 has the externally-managed-environment set, so this
flag is needed to let pip ruthlessly write to / of the container it
runs in. We could also use the flake8 package from alpine or use ruff,
but let's unblock it for now with this easy fix.

Import test_upstream_compat.py from pmaports.git, based on
test_upstream_compatibility.py and test_soname_bump.py with minor
adjustments. Make use of gitlab pages feature to publish a badge that we
can add to pmaports.git.

Currently, the test is failing because there are some compatibility
issues in pmaports that need to be addressed.
