[gnome-ostree] Support "bootstrap" annotation on modules

[Colin Walters <walters src gnome org>]

commit c709bc187375006bb18b6f4377a9111dde8b8b69
Author: Colin Walters <walters verbum org>

    Support "bootstrap" annotation on modules
    
    When given, this annotation says that while it will appear in
    buildroots, the module should not appear in the final trees.
    
    Used for the vala-tarballs-as-git module which we just use to
    bootstrap vala.
