Add support for booting PS3s from disk. This is still a little hackish until

we can find a way to get the information from petitboot or to guess it, so
the current algorithm is:

1. See if ps3disk3p1 (first GPT slice on OtherOS partition) exists, and if
   so try to boot it.
2. Otherwise, netboot.
