To ensure dracut does not load nouveau we need to explicitly disable it via
omit_drivers.
This change adds a method to drop in arbitary dracut conf files to an element
which are picked up by dracut-regenerate and included in the chroot where we
run dracut.
The disable-nouveau element just adds a conf file with
`omit_drivers += " nouveau"`
The default dracut conf files in /usr/lib include a similar file to omit the
nvidia kernel modules.

This seems to miss the exit code of the dracut process, which actualy
caused some issues in I8511669e188717494daf2bc1384a6dd346f942a4 where
it would have been much clearer to stop after the initramfs generation
failed.
Add some debug messages, and catch any errors from the final call.

When using combined with rhel7 image, the unregister of repos
has already happened, because it is executed under 60- ordering.
As dracut-regenerate may need to install extra packages for it,
it causes this step to fail, because it cannot find repos where
to pull the packages from.
