    tracker-miner-fs: Interpret GFileInfo uint64 times as time_t
    
    This is a time_t underneath, and forcibly interpreting it as unsigned
    will break with negative times on platforms that internally define that
    type as signed (Linux and the GNU C library between them).
    
    Deal with it as a time_t on our side, and let up to the underlying
    implementation the interpretation of negative timestamps. This relies
    on undocumented implementation details and is thus a hack.
    
    Fixes: https://gitlab.gnome.org/GNOME/tracker-miners/-/issues/155
    
    (cherry-picked from commit ebec93102c88db8378a5d23ab7e5441762a6bb26)
