Keep epel repo dependency in rescue mode for openstack_buid_packages …

…role

Mock package is needed by dlrn to build openstack package
and is shipped by delorean-antelope-build-deps repo.

Rest of the deps is already provided by repo-setup repos.
So we donot need to enable repos here.

This pr move the epel package installation in rescue mode.

openstack-k8s-operators#1246 syncs
the repo-setup repos to /etc/yum.repos.d directory and drops existing
repos.

epel-release package comes from extra-commons centos repo defined in
centos-addons.repo. Since repo-setup deletes the existing repos.
So the epel-release package installation fails which is expected.

In order to fix, we are going to install epel-release from url
instead of packages.
