Most of these dependencies are available in environments where the bz*
tools will be executed. I think it would be better to simply remove the
absolute /usr/bin and /bin references such that grep, sed etc
invocations are picked up from PATH instead.

The "xz*" equivalent tools seem to do that. The rationale being that
bzip2 is often needed early in bootstrapping, and adding those inputs
would complicate the dependency tree. Although I admittedly haven't
looked at how bzip2 is used in Guix bootstrap. Thoughts?
