    build: Only run tests if introspection is enabled
    
    A build with -Dintrospection=false will fail if tests are ran.
    
    The integration tests added by commit 77b67c702 are written in
    Python and require gobject-introspection bindings to be generated.
    
    meson errors out with:
    ../tests/meson.build:7:0: ERROR: Unknown variable "gnomebt_priv_gir".
