iio: use timespec64 based interfaces for iio_get_time_ns()

Browse Source 
We have replacements for all the deprecated timespec based interfaces now,
so this can finally convert iio_get_time_ns() to consistently use the
nanosecond or timespec64 based interfaces instead, avoiding the y2038
overflow.
