[tracker-miners/wip/carlosg/time_t] tracker-miner-fs: Interpret GFileInfo times as time_t

    tracker-miner-fs: Interpret GFileInfo 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.
