dracut-ramdisk: fix support for elements with ramdisk-install.d

Browse Source 
Copy all of TMP_MOUNT_PATH into the ramdisk so that
ramdisk-install.d actions are respected.

Includes a workaround for a bug in Dracut that caused the copy
to fail.

Also moves init instead of copying it so we don't conflict with
the Dracut init.
