[Rd] fix for save()'ing RAW on PPC (and other big endian platforms)

[Byron Ellis]

OutByte should take a byte, not an int. Writing the first byte of an  
int is only going to work on little endian systems.

serialize.c:262
-static void OutByte(R_outpstream_t stream, int i)
+static void OutByte(R_outpstream_t stream, Rbyte i)
