time: fix quickcheck test to avoid wraparounds
When we call time.Unix(s, ns), the internal representation is
s + 62135596800, where 62135596800 is the number of
seconds from Jan 1 1 to Jan 1 1970.
If quickcheck generates numbers too close to 2^63,
the addition can wraparound to make a very negative
internal 64-bit value. Wraparounds are not guarded
against, since they would not arise in any reasonable program,
so just avoid testing near them.
Fixes #52409.
