OBS: add osmocom-next-packages.sh

Fill the "next" feed with source packages generated from the "next"
branch of each Osmocom project, if it exists, with fallback to the
"master" branch. Implement as wrapper around osmocom-nightly-packages.sh,
so we don't duplicate code and don't need to add more logic to the jenkins
job.

Adjust all osmo_obs_prepare_conflict calls. Add a comment line on top of
each osmocom-*-packages.sh script stating the feed they can be used with.
