Updates for ostree-container phase

This patch connects the phase into the main script, and adds other
modifications:

* The archive is now stored in the images/ subdirectory in the compose.
* Documentation is updated to correctly mention that variant repos are
  not available.
* Configuration for path and name of the final archive is dropped. There
  are reasonable defaults for this and there's no point in having users
  configure it.
* The extra message for the archive is no longer sent.
* The pungi-make-ostree utility is no longer required in the buildroot.

The pungi-make-ostree utility doesn't do any significant work. It
modifies configuration files (which can happen on the compose host), and
it starts other processes.

This patch changes the ostree-container phase to no longer need the
script in the buildroot. Instead, the utility is called on the compose
host to do the config manipulation and output the needed commands. Those
are then passed into the runroot task.
