[RFC PATCH] bitbake.conf/sanity: Add dependency on host xz

[RFC PATCH] bitbake.conf/sanity: Add dependency on host xz

[Richard Purdie]

Times change and xz is becoming the defacto compression format and
utility. Adapt to the times and assume that the system provides xz.

This leads into us being able to use xz for sstate instead of gzip.
