realtek: image: switch cameo devices from gzip to lzma

The cameo based RTL83xx devices have a simple U-Boot that only
supports gzip compression. Actual models are mainly D-Link
DGS-1210 and the Apresia Light GS120GT-SS. Reduce the image
size by ~1MB by switching over to lzma compression and rt-loader.
