Since gnuradio-runtime is compiled with log4cpp, all plugins that need
gnuradio-runtime (which is all of them probably) need log4cpp as well.
Add python.pkgs.cheetah to inputs of gr-osmosdr as it somehow started to
be needed.
@the-kenny did a good job in the past and is set as maintainer in many package,
however since 2017-2018 he stopped contributing. To create less confusion
in pull requests when people try to request his feedback, I removed him as
maintainer from all packages.
