refclock: require new samples to have newer timestamp

If all or most SHM/SOCK samples collected in a polling interval had the
same local timestamp, the dispersion could end up as nan, which could
trigger an assert failure later in the code.

Before accumulating a refclock sample, check if the timestamp is newer
than the previous one.
