[meta-gnome][PATCH 3/3] dconf: make gtk+3 dependency optional

[andreas.kling@gmail.com]

From: Andy Kling <andreas.kling@peiker-cee.de>

  dconf requires gtk+3 only for dconf-editor and is useful
  even on systems without gui.

  add PACKAGECONFIG for editor, enable it by default if x11
  is present in DISTRO_FEATURES

  add gtk+3 to DEPENDS only if editor is present in PACKAGECONFIG

  add x11 to REQUIRED_DISTRO_FEATURES only if editor is enabled

  Note: editor will be dropped from dconf in version 0.23.1
