build/jam/ppc: Fix PowerPC boot after hrev53614

* "xorriso doesn't support much of the mkisofs options"
* Dropping the hfs map made our bootloader no-longer get
  mapped as :tbxi which means qemu + Apple devices refused
  to boot it.
* Switch to genisoimage which can generate the correct image.
  (xorriso -as genisoimage doesn't work either)
