network-manager: support a defaults file in the init script

Sometimes it is useful to pass some parameters to NetworkManager when it
starts (e.g. --log-level) instead of editting NetworkManager.conf. Allow
the user add a file with a NETWORKMANAGER_ARGS variable containing such
flags. This is simpler than overriding the whole startup script (e.g. by
means of a rootfs overlay).
