Take advantage of module autoloading when mounting images as loop
* Make first /dev/loop0 device at archiso install hook. * Remove unneeded losetup, all is done directly via mount. * Images are now mounted on /tmpfs/mnt/image-name instead of /tmpfs/mnt/loopN, removing unneeded counter. * Add some variables to make code more readable.
