    docker: rebuild: if building fails, try a --no-cache build
    
    Building a docker image depending on a debian upstream has the problem that an
    intermediate build result will depend on an APT package archive that is
    probable to become outdated. It's necessary to do an 'apt-get update' regularly
    to get the newest package archives and be able to install new packages. We
    never know which 'apt-get install' steps we might be editing, so we'd have to
    add an 'apt-get update' before each, or use an ADD line to find out whether the
    package archive has changed, before each and every apt-get install step. We're
    likely to miss those in the future, and it would be a large, complex change.
    
    Instead, try to build the docker image with --no-cache in case a cached build
    has failed. This should fetch the most recent debian upstream with a proper
    archive.
    
    Fixes the current problem that the rebuild_osmocom_jenkins_image.sh is stuck on
    various build slaves, should trigger a --no-cache build on each slave.
