Silence Clang 10 trunk -Wdeprecated-volatile in GLib for now

See <https://gitlab.gnome.org/GNOME/glib/merge_requests/1170> "Avoid C++20
deprecated assignment to volatile" for a potential fix in GLib (but also see my
question at <https://github.com/llvm/llvm-project/commit/
4a6861a7e5b59be24a09b8b9782255d028e7aade#commitcomment-35540755> "[c++20]
P1152R4: warn on any simple-assignment to a volatile lvalue" whether that Clang
warning is actually wanted here).

With glib2-devel-2.62.1-1.fc31.x86_64, the suppressed warnings looked like

> libreofficekit/source/gtk/lokdocview.cxx:327:1: error: use of result of assignment to object of volatile-qualified type 'volatile gsize' (aka 'volatile unsigned long') is deprecated [-Werror,-Wdeprecated-volatile]
> G_DEFINE_TYPE_WITH_CODE (LOKDocView, lok_doc_view, GTK_TYPE_DRAWING_AREA,
> ^
