Add disabling source inclusion

Not all users care about source packages, so let's make life easier for
them. With the new option, the tool will not do anything about source
rpms, including not printing a warning for each RPM.

 # Changelog
 
+## Unreleased
+
+### Added
+
+- Inclusion of source packages in the final manifest can now be disabled with a
+  toplevel config option `noSources: true`. This is mostly useful for cases
+  where there are no source repos available to silence the many warnings.
