time: Change k_clock nsleep() to use timespec64
struct timespec is not y2038 safe on 32 bit machines. Replace uses of
struct timespec with struct timespec64 in the kernel.
The syscall interfaces themselves will be changed in a separate series.
Note that the restart_block parameter for nanosleep has also been left
unchanged and will be part of syscall series noted above.
