Change #278798

tests: stat: check nanosecond precision away from the Epoch
The existing checks all use a timestamp only 67413 seconds after the
Epoch, which a double can still represent exactly to the nanosecond, so
they do not detect a formatter that goes through floating point.  They
also never look at a timestamp before the Epoch, where the fraction has
to be truncated towards minus infinity.

* tests/stat/stat-nanoseconds.sh: Also check %Y, %.Y, %.3Y and %.9Y on a
2026 timestamp and on a timestamp shortly before the Epoch.
