ci: drop the compliance tag from REUSE check

Historically the REUSE check was routed to a dedicated but slow machine
that guaranteed that no CI would be stuck waiting on the miniscule
compliance job.

With the Eclipse migration and CI/CD being slightly out of our control,
it's just more convenient to drop this tag rather than request
configuration change in the instance.
