[PATCH rumpkernel] prune.sh: Remove ~1.1G of currently unused bits.

The rumpkernel archive is ridiculously large.  It manages to grow so big
mainly by adopting the evil practice of bundling other packages.  The
archive contains copies of many GNU utilities, a copy of llvm, and even
a copy of postfix.

The archive can most probably be pruned a lot further without
consequences, but this is a helpful start.  I'm built the Guix
rumpkernel using this pruned archive and it works fine.  The same list
of librump* libraries are built and there are no messages in the build
log that suggest things are missing.

Because the patches are so big I'm only sharing the prune.sh script that
will create some 'prune: ...' commits.
