containers: Use Fedora 30's test Errata for libcomps
until they release the Errata.
So that python3-libcomps can have .egg-info metadata available for pip to see that libcomps is already satisfied for pulp_rpm.
They already released the corresponding Errata for Fedora 31, so this should be very safe.
Also, cleanup currently unneeded -devel packages.
[noissue]
re: #5840 as a user of pulp_rpm_prerequisites I have libcomps installed from pypi https://pulp.plan.io/issues/5840
