time: Change types to new y2038 safe __kernel_itimerspec

Browse Source 
timer_set/gettime and timerfd_set/get apis use struct itimerspec at the
user interface layer.  struct itimerspec is not y2038-safe.  Change these
interfaces to use y2038-safe struct __kernel_itimerspec instead.  This will
help define new syscalls when 32bit architectures select CONFIG_64BIT_TIME.
