Subject: Added vfat support to mount /dev/archiso

fstype from klibc don't detect a vfat formatted blockdevice when try to
mount /dev/archiso to /bootmnt. Some users don't use the recommened
method with dd to bring the image to their USB stick. If they for ex.
use Unetbootin to put the iso image on their (v)fat formatted stick they
got lost with a kernel panic cause fstype won't detect vfat, so the
mount and the later squashfs bindings traps.
