Adjust maximum number of connections for per user

Browse source 
After logging into the desktop environment, it will consume a lot of dbus connections.
When starting some services (such as VNC),  there will be encounter the error of dbus user connection reaching the maximum limit.
the error log below:
```
The maximum number of active connections for UID 0 has been reached (max_connections_per_user=256)
```

Therefore, adjust the maximum connection  limit for per user appropriately  to avoid the error.
Ensure the normal operation of upper level dependent programs.
