[gobject-introspection] Automatically install pre-commit hook

[Martin Pitt <martinpitt src gnome org>]

commit aae598e1e60aad3d30b21c398f55e9b6944be971

    Automatically install pre-commit hook
    
    Instead of telling the user to do so and failing, we can just install the hook
    ourselves. This saves the user some trouble and more importantly avoids
    breaking tests in jhbuild continuous integration setups.
