[glib] Remove length parameter for g_settings_[gs]et_strv

[Ryan Lortie <ryanl src gnome org>]

commit bf9edb5cd5a75a4bc9946f0ef106c3d541fdb89f

    Remove length parameter for g_settings_[gs]et_strv
    
    Length of the array is redundant since it's NULL-terminated. This is not
    consistent with many GLib and GTK+ functions, and adds complexity with
    no real gain, while these convenience functions should be kept simple.
    
    Closes bug #620312
