Pushed, thanks!

IMHO, the modules in gnu/packages are quite a mess. There are many
modules with only one or a few packages (less than 10). At some point,
we'll have to revisit this, and figure out a better organization.

Debian has a category for HAM Radio packages. So, I thought it's ok to
create ham-radio.scm for rtl-sdr.

I'll look into it.
