only pass WEAVESCOPE_DOCKER_ARGS to actual probe/app start

and not all the help, version, etc, etc docker runs.

In particular this allows passing `--restart=...` in
WEAVESCOPE_DOCKER_ARGS. Previously that would break since the
non-probe/app docker runs supply `--rm` (as they should) which is
incompatible with restart settings.
