ftl_check/ftl_format/nftldump: use existing mtd_swab.h header

We already have a helper header for swapping bytes as needed, so cut
the ftl tools over to that rather than re-implement things.

I don't actually have any devices with this kind of flash, so I can't
runtime test it.  But things *look* ok to me :).
