mkosi: Enable EPEL for CentOS Stream tools tree

We need packages from EPEL to be able to build CentOS Stream images
with a CentOS Stream tools tree so enable it. This is broken on CentOS
Stream 10 but given using a CentOS Stream tools tree is broken without
EPEL as well, we might as well enable it and just wait until the packages
are added to EPEL 10.
