Fixes FS#17182: copytoram=y does not work with aufs

The solution is simple, just use a directory outside aufs tree.

* If copytoram=y, then another tmpfs is mounted but on /tmpfs.sqfs
* Add a new option: tmpfs_sqfs_size= (default to 75%)
* Lock cdrom drive is not locked if copytoram=y

* 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.

Next version of mkinitcpio > 0.6.2 implements mount hook functionality.
So can avoid skipping normal flow of main init script, and removing common
end code with it.

I missed a hook last time, so it was producing some
scary, but harmless output.
