Subject: Let gnome-tweak-tool and gnome-control-center have gnome-shell as input

Hi,

Currently gnome-tweak-tool and gnome-control-center doesn't have gnome-shell
as input (in gnome.scm package definition). This results in issues when some
new package with gsettings schemas is installed.

without access to gnome-shell schemas, gnome-tweak-tool won't ever work, so
it is mandatory. And for the case of gnome-control-center, the keyboard panel
segfaults if gnome-shell schema isn't present. But since gnome-shell may not
be used by all g-c-c user, it may not be good to have a hard dependency on
gnome-shell, but if installed, the schemas of gnome-shell should too be added
as input (is it possible to do so?)

How to reproduce (hopefully gnome-shell is being used):
0. Install gnome-control-center and gnome-tweak-tool.
1. install some gnome application (eg: guix package -i gnome-calculator)
   It doesn't matter if you have already installed the package
2. run gnome-tweak-tool or run gnome-control-center and click Keyboard

result:
0. gnome-tweak-tool:

WARNING : Shell not running
None

I suppose the problem doesn’t manifest when using
‘gnome-desktop-service’, because XDG_DATA_DIRS & co. are set such that
the gnome-shell schemas are found.

I would think that’s enough in practice, no?  I doubt these are used
outside of a pure GNOME setting.

Also, gnome-shell depends on gnome-control-center, so
gnome-control-center cannot depend on gnome-shell.

Thanks,
Ludo’.
