rec: Work around a RRSIG year-2038 issue in the negcache unit tests

On 32-bit OS with a signed 32-bit `time_t`, we have a known issue with
dates later than 2038 in `RecordTextWriter::xfrTime()`. For now we will
just use an earlier date than 2038 in these tests since the date has no
relevance there.
