disk - add flag to use underlying psize

 * If the top (disk subsystem) psize fails, try again with the
   underlying raw device psize if the DSO_RAWPSIZE flag is set for the
   disk.

 * This allows for disk devices and slices without a proper disklabel to
   return a correct psize, which in turn allows the device to be used
   for swap.

 * Previously that behaviour was integrated with the DSO_DEVICEMAPPER
   flag.
