update_engine: Add XZ compression for CrOS
This patch implements XZ compression for Chrome OS. It is only activated
for only delta payload at this point. The XZ compression is typically
slower than Bzip2 to compress, but faster to decompress. However, it
uses slightly higher memory in decompression. It compresses about 5%-10%
better than the current Bzip2.
