[PATCHSET] Updates for Mageia mock build targets

[Neal Gompa]

Hello all,

Since my last email two months ago[1], I've been working steadily
towards the completion of our infrastructure bringup for supporting
COPR oriented workflows. I've added tito and copr CLI tools to the
distribution to enable CLI-centric workflows as well.

While we are still working on bringing up MirrorBrain for metalinks,
we have a rudimentary script that generates a yum-style mirrorlist
that DNF and mock can consume. This has allowed me to update and
expand the Mageia build target configuration for mock, which I have
added to our mock package.

The patches attached to this email update and expand the Mageia
configs, including adding Mageia 6. Note that the Mageia configuration
for armv7hl does not yet work because we are still in the process of
completing the build. We've estimated that it should be finished
within the next couple of days, and then the switch will be flipped to
make it public. This is why the Mageia armv7hl configuration files are
in a separate patch. While I have applied the entire patch series to
the Mageia mock package, it is up to you on whether you wish to
include the armv7hl configuration files or not right now.

These patches should apply cleanly on top of the devel branch for mock.
