Replace + with - on gitlab

Due to the issues with using + in the name of packages, like with gtk+2.0, Apertis decided to replace + by - in several cases, which can be used as default.

The current code took the approach of escaping the +, but that is not really needed for the folding/branching process which rely on package names.
