Replace bz2 rootfs tarball compression with xz compression 

We tested all tarball compression formats supported by poky, and although bz2
has faster (de)compression time, xz is better in terms of compression ratio:
for all of the rootfs tarballs generated for our currently supported
images/platforms (15 at the moment), the xz format saves an average of 30 MiB
per tarball compared to bz2, totalling up to 450 MiB.

No extra dependencies are pulled in, since xz-native is already being pulled in
for all of our image builds, so the only drawback to this change is the
increased compression time (+7.34s on average per tarball).
