time/namespace: Export init_time_ns and do_timens_ktime_to_host()

timens_ktime_to_host() in compares the current time namespace against
init_time_ns for the fast path. It calls do_timens_ktime_to_host() for the
offset case. Both symbols are needed at link time by any caller of the
inline.

All current callers are builtin, but ntsync can be built as module, which
prevents it from using it.

Export both with EXPORT_SYMBOL_GPL.
