Subject: OBS: make nightly packages conflict with latest

Add conflicting dummy packages osmocom-nightly and osmocom-latest, and
make all packages from each repository depend on the right one.

As usually, the latest packages will only get changed when a new release
appears. So the dependency will get introduced after tagging a new
release. I have tested in an own OBS namespace, that everything works as
expected.
