[glib] inotify: stop using constructor()

[Ryan Lortie <desrt src gnome org>]

commit 700677de512e19060337121692058627fe717d24

    inotify: stop using constructor()
    
    and start using the new start() vcall on the local monitor classes.
    
    I only port inotify because I am uncomfortable making changes to the
    other monitor backends without having a way of testing them.
