bitbake: bb/main.py: avoid starting server when not needed

Fixed 1:
$ . ../poky/oe-init-build-env-memres .
$ bitbake -m
$ bitbake -m # shutdown it again
$ bitbake -m
Starting bitbake server...
Terminated bitbake server.

It starts the server and kill it which is redundant.

$ bitbake -m
$ bitbake --status-only
Starting bitbake server...

It starts the server which is not what we need.
