Prepare to use ssh inside the docker container to check if tarballs
already exist, see the next patch.
Remove the '' around UserKnownHostsFile as using SSH_COMMAND in the next
patch without rsync fails otherwise with:
command-line: line 0: Bad configuration option: 'userknownhostsfile

Add a jenkins.sh that does the same as the previous lengthy shell
command in the jenkins-job-builder file, and add
osmocom-release-tarballs.sh. This makes it easier to test the
script, and only patching one repository is needed from now on when
changing to a newer debian version.
