vlc: Disable Lua support to work around build error

Work around the error below, by disabling the Lua support [1]. VLC is
not used that much, and the feature is not needed.

```
  CC       lua/libs/liblua_plugin_la-configuration.lo
/dev/shm/bee-root/vlc/vlc-3.0.0-0/source/modules/lua/demux.c: In function ‘vlclua_demux_peek’:
/dev/shm/bee-root/vlc/vlc-3.0.0-0/source/modules/lua/demux.c:55:13: error: implicit declaration of function ‘luaL_checkint’ [-Werror=implicit-function-declaration]
     int n = luaL_checkint( L, 1 );
             ^
```
