syslinux: support ext2/3/4 device

* Support ext2/3/4 deivce.
* The open_ext2_fs() checks whether it is an ext2/3/4 device,
  do the ext2/3/4 installation (install_to_ext2()) if yes, otherwise go
  on to the fat/ntfs.
* The ext2/3/4 support doesn't require root privileges since it doesn't need
  mount (but write permission is required).

Next:
* Get rid of fat filesystem from the boot image.

These patches have been sent to upstream, we may adjust them (maybe put
the extX support to syslinux-mtools), I will go on working with the
upstream.
