install: Add option to install radio modules.

Add an option (--rpt) to install the radio modules (e.g. app_rpt, etc.).
These modules used to be in the Asterisk tree, but were removed in
commit asterisk/asterisk@4585000
and a few other commits. The modules are currently being maintained in
a third-party repo, and this option pulls the files into the source tree.
