    introspection: Fix parallel builds
    
    One needs to add an explicit dependency between the gir files and the
    .la libtool wrapper as this dependency is not added automatically by
    Makefile.introspection. Not adding these breaks parallel builds as make
    does not wait for the .la to be generated before launching g-ir-scanner.
