[Buildroot] [git commit] pulseaudio: correct libgtk3 handling

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=7006bff9b3cda17b36bd45e94426b64f270c625e
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The gtk3 support uses X11 specific functionality, so it should only be
enabled if the X11 backend is enabled.

Fixes:

http://autobuild.buildroot.net/results/3fb/3fbbdbf39e29319b349b2cf155397a121f24bf28/

And many others.
