Nirbheek Chauhan 4e7d3b42ec meson: Pass native: false to add_languages()
This is needed for cross-compiling without a build machine compiler
available. The option was added in 0.54, but we only need this in
Cerbero and it doesn't affect older versions so it should be ok.
Will only cause a spurious warning.
