Filip Bozuta ddcbde157d linux-user: Add support for 'rt_sigtimedwait_time64()' and 'sched_rr_get_interval_time64()' 
This patch implements functionality for following time64 syscalls:

*rt_sigtimedwait_time64()

    This is a year 2038 safe variant of syscall:

    int rt_sigtimedwait(const sigset_t *set, siginfo_t *info,
                        const struct timespec *timeout, size_t sigsetsize)
    --synchronously wait for queued signals--
    man page: https://man7.org/linux/man-pages/man2/rt_sigtimedwait.2.html

*sched_rr_get_interval_time64()

    This is a year 2038 safe variant of syscall:

    int sched_rr_get_interval(pid_t pid, struct timespec *tp)
    --get  the  SCHED_RR  interval  for the named process--
    man page: https://man7.org/linux/man-pages/man2/sched_rr_get_interval.2.html

Implementation notes:

    These syscalls were implemented in similar ways like
    'rt_sigtimedwait()' and 'sched_rr_get_interval()' except
    that functions 'target_to_host_timespec64()' and
    'host_to_target_timespec64()' were used to convert values
    of 'struct timespec' between host and target.
