    Set log domain to Tracker
    
    This fixes a regression introduced by the Meson port, where this package
    didn't declare a GLib log domain. Fixing this means that you can once
    again use the environment variable `G_MESSAGES_DEBUG=Tracker` combined
    with `TRACKER_VERBOSITY` to show debug messages only from Tracker.
    Without this fix, `G_MESSAGES_DEBUG=all` is needed to enable the
    messages to be printed, but this may enable output from other packages
    too.
