The abuild package has been forked to temp/abuild and
extra-repos/systemd/abuild in the past. The systemd one is legacy from
the initial systemd repo bootstrap method that is currently broken and
will be replaced soon (see MR 6440). While the new one is not ready yet,
this package is currently not useful so remove it to fix the failing
upstream-compat check (currently it is on a different version than
temp/abuild).
