[glibc] time: Introduce glibc's internal struct __itimerspec64

    time: Introduce glibc's internal struct __itimerspec64
    
    This change provides the glibc's internal struct itimerspec representation,
    which is explicitly supporting 64 bit time (by using struct __timespec64).
    
    Such representation is necessary to provide correct time after Y2038
    (time_t overflow) on devices with __TIMESIZE == 32.
