Subject: [PATCH] um/time: use timespec64 for persistent clock

This read_persistent_clock() implementation is the only remaining
caller of set_normalized_timespec(). Using read_persistent_clock64()
and set_normalized_timespec64() instead lets us remove the deprecated
interface in the future and helps make 32-bit arch/um get closer to
working beyond 2038.
