Subject: [PATCH] python-rtmidi: add alsaLib and libjack2 deps

python-rtmidi includes the rtmidi C++ library as a submodule (which is
unfortunate since rtmidi is separately packaged in nixpkgs already) and wraps it
using Cython.  Without these dependencies, python-rtmidi won't build support for
ALSA or jack into the compiled rtmidi, and will only have the 'dummy' API
available.
