[LinuxBIOS] s2881 build broken

[Lu, Yinghai]

If the compressed_stream is enabled, 
1. when build the payload.nrv2b_x, 
	if ratio <= 1, the head four byte will be "0x5a5a5a5a", and use
ori payload.
	else the head four byte will be "0xaaaaaaaa", and used
payload.nrv2b image instead.
2. when rom_steam_init is called, it will check the head signature to
decide if uncompress it, or just use it.

that will need another 4 byte header before the stream.
