bzip2 has been unmaintained for a long time. For a while now, there has
been maintainership, resulting in the release of 1.0.8. At the same
time, there is now a master branch (version 1.1.x) which supports meson
and cmake as build systems.
This commit adds the current HEAD of the master branch (1.1.x). In the
future we may want to use this one instead of the older and patched
1.0.6 we currently have.
