    Minor improvements to Docker support.
    
    If you run a 32-bit Docker image on a 64-bit host machine, then
    'uname' and 'arch' report the system architecture type as 64-bit (e.g.
    "x86_64"), because Docker images share the host kernel. This
    occasionally confuses client programs (in particular the 32-bit
    cov-build) into refusing to run.
    
    The fix is to wrap all the processes we run inside the container in an
    invocation of 'setarch', which adjusts the architecture value seen by
    userland processes' queries. So now we permit the config file to set a
    variable 'docker_setarch_foo' alongside 'docker_foo', and if it's set,
    we wrap the bob-delegate-server invocation in a setarch.
    
    Also, while I'm here, assign a fixed hostname to containers, so that
    if the hostname shows up anywhere in the output, it will be at least
    vaguely meaningful.
