    build: distcheck fails trying to remove a srcdir file
    
    When we referenced $(srcdir)/libfolks_telepathy_la_vala.stamp, we were
    telling automake that it was OK to delete it from the srcdir, which is
    considered bad form. By referring to it from the builddir, we don't
    implicitly suggest it can be deleted (as it is as a part of its creation
    process).
