dpranke@ PTAL.  libxkbcommon* were needed for wayland keyboard stuff (tonikitoo@
can clarify if needed).

Unfortunately that package was only available in the universe repo, not main, so
I needed to modify sysroot-creator.sh to add the new functionality.  (Note that
we would not have to add this if we were using the jessie or trusty sysroot...)
