fix: chown server-info file by client user in compose mode - alt fix

[mkundu1]

This PR removes the FLUENT_SERVER_INFO_PERMISSION_SYSTEM env var for compose launch. The server writes the server-info file with the default 600 permission. The file owner is subsequently changed to client-user subsequent using a docker exec call, so the file can be read in the client side.
