sound.js imports from bad path, on x86_64

[ferdnyc]

sound.js contains the following code, to force the import path for Gvc:

const GIRepository = imports.gi.GIRepository;
GIRepository.Repository.prepend_search_path("/usr/lib/gnome-shell");
GIRepository.Repository.prepend_library_path("/usr/lib/gnome-shell");
const Gvc = imports.gi.Gvc;

That fails, at least on my system (Fedora 26 x86_64), with the following message logged to the journal:

This is because /usr/lib/gnome-shell/ is an invalid path, and the Gvc-1.0.typelib file lives in /usr/lib64/gnome-shell/. Changing sound.js to use /usr/lib64/gnome-shell eliminates the error.

prepend_search_path() and prepend_library_path() don't throw exceptions, so it should be safe just to add more. I think this will fix it, thanks for reporting.
