Split fedabipkgdiff to its own subpackage

This tool is very specific, and only useful to Fedora developers, not
all developers.

It also has lots of dependencies which aren't required by the other
tools.

Splitting it to its own specialized package makes the main package, with
its library and utilities, much lighter.

 %changelog
 * Wed Mar 13 2019 Mathieu Bridon <bochecha@daitauha.fr> - 1.5-4
 - Remove unnecessary dependencies: python3-unittest2 and wget which
   was referred to twice.
 - Better group dependencies: Many dependencies are only required for
   fedabipkgdiff, so let's put them under the right conditional.
