    daemon: Enable debugging for the main daemon by GVFS_DEBUG
    
    This is currently more-or-less just a cosmetic issue, because there aren't
    any debug prints in the main daemon, and because other daemons are
    spawned with the same enviroment. However this fixes debugging for the
    proposed admin daemon, because GVFS_DEBUG environment variable is not
    passed in pkexec environment.
