Ending phases with #t is no longer required on core-updates, and we can
stop doing it on master and staging already too, to save us the hassle
of editing them out at some later point in time :-)

This inputs field seems unnecessary, especially we don't want to add a
dependency to Python 2, which is slowly being carved out of Guix.

I personally prefer the more compact (and common?) indentation of the
licenses list as:

    (license (list license:expat        ;library
                   license:bsd-2))))    ;python bindings

It's down to personal preferences, but I tend to value compactness in
thousand lines long modules :-).

I've made the following changes:
