Ensure we trigger building new OBS packages first, then wait plenty of
time until the binary packages are available (and run jobs in the
meantime that don't need them), and only after that we run the jobs
that need the binary packages.
Otherwise TTCN3 jobs may test the packages from the previous day, and
some jobs may fail completely due to packages not being completely built
yet. For example, yesterday the new Osmocom CNI releases were tagged,
which means the :latest packages also need to be rebuilt (-> building
all OBS packages takes longer). The osmocom-release-manuals and
-tarballs jobs failed, because the new binary packages were not
available yet when they ran.
Change all timers to the format "H 20 * * *" to have a deterministic
hour and semi-random minute based on the job name.

No need to mirror these images if we don't use them anymore.
Remove debian 8 and 9, and ubuntu zesty. The latter is the codename for
ubuntu 17.04, which is a non-LTS and was unsupported since 2018-01-13.
