  1. Use tini when using cvmfsexec to handle signal propagation 

    We have an issue where if the container uses cvmfsexec to mount repos,
then a SIGTERM (as sent by docker stop) won't shut it down and we have
to wait for docker to time out and send SIGKILL.

This is because cvmfsexec is pid 1 inside the container, which is
special, and we have to have it explicitly forward the signals to the
child processes.  If we don't use cvmfsexec, then supervisord is pid 1,
and signal propagation is handled.

This commit adds `tini`, a small init system, to handle signal
propagation; it is only used when we're using cvmfsexec.
