time: Change k_clock timer_set() and timer_get() to use timespec64

Browse Source 
struct timespec is not y2038 safe on 32 bit machines.  Replace uses of
struct timespec with struct timespec64 in the kernel.

struct itimerspec internally uses struct timespec.  Use struct itimerspec64
which uses struct timespec64.

The syscall interfaces themselves will be changed in a separate series.
