Jan Kiszka 06aae60b65 container: Disable git safe.directory when running without kas-container
This is for the sake of the gitlab-ci runner which does not properly
aligns the ownership of the repo it checks out with the UID:GID of
our builder user. Reason not yet understood and hard to debug (logging
of the runner is incomplete).

Work around this issue by disabling safe.directory checks in case the
container is called without kas-container as wrapper (means, when it is
called without setting "--user=root"). This preserves git's checks for
the common interactive case, the more critical one.
