[pxebs] Correct endianness of PXE type

The PXE type field is canonically little-endian, but the pxebs command
treats it as big-endian in converting the type number passed on the
command line to a field value to search against. Fix, to prevent the
necessity of incantations like "pxebs net0 1536" to select menu item #6.
