Add comment about rootful Docker permissions at container start

Browse Source 
Rootful Docker recreates volume mount points as root on start,
preventing the GNS3 process from writing files into node directories
while the container is running. self._fix_permissions() would resolve
this but is currently only called at container stop time.
