Packit: remove EPEL jobs, separate out ELN jobs

Removing EPEL (RHEL) jobs from here, as we have removed them from our
other projects as well. RHEL copr envrionments are often out of date,
leading to failed builds and tests.

Testing on CentOS Stream should suffice to guarantee that whatever
enters RHEL has passed upstreawm tests.

This commit also separates out ELN jobs so that fedora copr targets can
be conveniently reused in TMT tests that will be added in future
commits.
