contrib/jenkins.sh: Update script to fix several issues and use recent
osmo-ci utils

Previous script didn't clean workspace and git repositories were
allegedly not being updated, hiding build failures against newer deps.

Currently cellmgr-ng is not being maintained and fails to build against
recent libosmo-sccp. For that dep repo, tag "old_sua" is used since
after that tag, APIs changed considerably and it is known that
cellmgr-ng cannot build starting from there.

It's up to whoever wants to maintain it to make changes in cellmgr-ng to
support newer libosmo-sccp.

While building with new jenkins.sh script and "old_sua" tag, still there
are some build issues (mostly related to build system), like some
Makefile.am files missing some LDFLAGS. Some of them are fixed in
follow-up patches. Some other are left as an exercise for whover wants
to revive this repo.
