    libtracker-miner: Avoid warning on EXDEV from fanotify_mark()
    
    This is sadly something that may happen with btrfs subvolumes, so
    will be seen frequently in certain environments, or might cause
    the test suite to fail for no (unforeseen) reason. Convert this
    errno into a g_info() what will not be logged by default.
    
    Closes: https://gitlab.gnome.org/GNOME/tracker-miners/-/issues/212
