[gnome-shell] shell: Drop questionable vfuncs

    shell: Drop questionable vfuncs
    
    Both ShellAppSystem and ShellTrayManager are used as singletons, which
    significantly reduces the usefulness of inheritance - it's unlikely for
    extensions to inherit from them anyway (AND use any of the vfuncs), so
    drop them to allow defining the types as final in an upcoming commit.
