Set an existing Icon name in the Applications' panel desktop file

While we dynamically append --symbolic to the icons while creating
the sidebar model in
https://gitlab.gnome.org/GNOME/gnome-control-center/-/blob/master/shell/cc-shell-model.c#L270
There are automation tools (such as rpmdiff) that parse desktop files
and verify whether their Icon= matches to an existing file in the
icon theme package.

preferences-desktop-apps doesn't exist in adwaita-icon-theme but
preferences-desktop-apps-symbolic does.
