time: Correct the prototype of ns_to_kernel_old_timeval and ns_to_timespec64

In ns_to_kernel_old_timeval() definition, the function argument is defined
with const identifier in kernel/time/time.c, but the prototype in
include/linux/time32.h looks different.

- The function is defined in kernel/time/time.c as below:
  struct __kernel_old_timeval ns_to_kernel_old_timeval(const s64 nsec)

- The function is decalared in include/linux/time32.h as below:
  extern struct __kernel_old_timeval ns_to_kernel_old_timeval(s64 nsec);

Because the variable of arithmethic types isn't modified in the calling scope,
there's no need to mark arguments as const, which was already mentioned during 
review (Link[1) of the original patch.

Likewise remove the "const" keyword in both definition and declaration of
ns_to_timespec64() as requested by Arnd (Link[2]).
