ruffle: nightly-2022-02-02 -> nightly-2022-09-26

Description of changes

Although there isn't a changelog for Ruffle, quite a lot has improved since last nightly, including the beginnings of AVM3 support.

We now need a valid JRE (only during build, to run the ActionScript compiler) and for ruffle desktop, GTK+3. In order to avoid unnecessarily wrapping every binary, and also to avoid double-wrapping, wrapGAppsHook is used with dontWrapGApps = true, then we use "''${gappsWrapperArgs[@]}" in the existing call to wrapProgram for ruffle_desktop. We need the file dialog schemas, so gsettings-desktop-schemas is added to nativeBuildInputs. We need the glib hook that adds schemas to the XDG_CONFIG_PATH, so glib is added to nativeBuildInputs, and postInstall is changed to postFixup to ensure that gappsWrapperArgs is set for us.

I believe this is the minimal necessary changes to make sure that it will work properly.
