Hello Guix!

Here are a couple of patches to update StumpWM.  It now runs a testsuite
that relies on fiasco [0] so the first patch packages it.  I'm afraid
there doesn't seem to be a released version so this is packaging the
current HEAD of the git repository.  There is a tarball on github but it
looks like it's just a snapshot of the repository from 2014, it doesn't
seem to be a actual release.

Thanks!
Pierre
