The output for ``yum -v repolist all`` changes slightly in CentOS 8. There are
two specific changes:
1. EL8 is no longer trailing the repo name with release version and arch (i.e.
base instead of base/7/x86)
2. EL8 no longer adds a trailing newline on the last repo and instead has a line
with ``Total packages:``. This means the repo listed last will never show up.
A fix was introduced in #4566 however the tests still use CentOS 7 yum output
instead of dnf repolist output. One issue was still discovered where it was
including the ``Total packages`` line in the last repository. This includes a
regex for to work around that and fixes for the tests.
