Done! There is no issue at runtime(As far as I've seen). But i think we can have one more improvement:

These are all files that belong to pantheon-default-settings:
```
/etc/gtk-3.0/settings.ini
/etc/profile.d/gtk-csd.sh
/etc/profile.d/pantheon-filechooser-module.sh
/etc/profile.d/qt-qpa-platformtheme.sh
/etc/profile.d/qt-style-override.sh
/etc/skel/.config/plank/dock1/launchers/gala-multitaskingview.dockitem
/etc/skel/.config/plank/dock1/launchers/io.elementary.appcenter.dockitem
/etc/skel/.config/plank/dock1/launchers/io.elementary.calendar.dockitem
/etc/skel/.config/plank/dock1/launchers/io.elementary.music.dockitem
/etc/skel/.config/plank/dock1/launchers/io.elementary.photos.dockitem
/etc/skel/.config/plank/dock1/launchers/io.elementary.switchboard.dockitem
/etc/skel/.config/plank/dock1/launchers/io.elementary.videos.dockitem
/etc/skel/.config/plank/dock1/launchers/org.gnome.Epiphany.dockitem
/etc/skel/.config/plank/dock1/launchers/org.pantheon.mail.dockitem
/usr/share/glib-2.0/schemas/25_pantheon-default-settings.gschema.override
```
There is no need for those /etc/skel/* files. Since `dockitems` can be customized by user. Other 6 files can be package like `pantheon-session`. And also `25_pantheon-default-settings.gschema.override` needs to be reformed. 

So instead of fetching a repository [with lots of nonsense files ](https://github.com/elementary/default-settings/tree/master/debian) and information, we can have our own files that only needed by void-linux.
