Don't filter RPMs of reused components from a module that depends on itself
If a module has filters set and it buildrequires itself, issues occur
during component reuse. In that event, the filtered RPMs from the
previous module build will not be available in the buildroot because the NVRs
in the filters will match the RPMs from the reused component.
