Fix linking with gold by cleaning up lib dependencies.

- Remove pangoft2, we don't use it anywhere.
- Add gdk, fontconfig and freetype2 as dependencies of skia.  Gdk is
  used in platform_canvas_linux.
- X11, Xrender and Xext are used by the IPC system, so everything that
  depends on common, needs to link in those libs.  By moving the
  link_settings line into the libcommon.a target, all projects
  inherit these.
