systemsettings: dependencies fixed
https://github.com/void-linux/void-packages/pull/14593

Description:
Added dependency: gsettings-desktop-schemas.
Fixed license from GFDL-1.2 to GFDL-1.2-only.
If this dependency is missing (gsettings-desktop-schemas), the package crashes.
Departure Log: http://dpaste.com/1495W9R.
How to reproduce the problem:
We launch the package (systemsettings5), go to the section "Application Design" -> "Style of GNOME/GTK+ Programs" and try to change the GTK3 theme, a set of mouse cursors and "prefer a dark theme".
And this log shows the log of the package itself (systemsettings5) with this dependency: http://dpaste.com/3N42GFJ.
