    Disable gvfs's FUSE for the child session
    
    Gvfs-fuse-daemon processes from old sabayon sessions may keep running even after
    sabayon terminates.  When a new sabayon session is run, those old daemons may crash,
    and FUSE makes their .gvfs directories in the temporary home directory totally unreadable
    (they show up in 'ls -l' as having mode d?????????) - they can't even be stat()ted.
    So, we disable FUSE completely for GVFS in the child session.  Those sessions don't need
    to mount funny stuff, hopefully.
