[nautilus/extensions-build-dep] Ensure that extensions depends on generated headers

[Emmanuele Bassi <ebassi src gnome org>]

commit 900d2be31ccfc649623e1d8fab31c92a31371f38

    Ensure that extensions depends on generated headers
    
    The libnautilus-extensions internal dependency must include the
    generated enumeration header file, otherwise we may end up building
    targets that depend on the library prior to have the header properly
    generated.
