[nautilus] files-view: use GFile utilities

[Ernestas Kulik <ernestask src gnome org>]

commit 672ccbc4dbde12b9a91a1adf6758550cd114aef2
Author: Ernestas Kulik <ernestask src gnome org>
Date:   Sun Aug 7 11:21:28 2016 +0300

    files-view: use GFile utilities
    
    set_up_scripts_directory_global() currently uses the POSIX file
    interface, which is inconsistent with the rest of the code. This commit
    rewrites the parts of the function to use the GFile API.
