[rygel] core: Avoid 'this' before chaining-up to other constructors

[Zeeshan Ali Khattak <zeeshanak src gnome org>]

commit c2ac4eec4006507f735a97409607d47af41eeedc

    core: Avoid 'this' before chaining-up to other constructors
    
    Instead of using 'this' keyword (that will segfault as its being used
    before chaining-up to other contstructor) just make copy_str_list()
    static instead.
