Support using the internal NAND as the persistent /home for the OLPC

The OLPC's internal NAND is a really good idea to use for /home rather than
taking up the very hard to find RAM.  The NAND is default set up with a
/home on mtd0, so also do some magic so that we create our homedir under that
/home.
