Commits a7145f6bc et al. added a test to verify integer overflow
detection in interval_mul. The buildfarm has now reminded me that
you're not going to get integer overflow if timestamps ain't integers,
cf

I think the most expedient answer is just to remove that test case
in the pre-v10 branches. It's already served its purpose by showing
that the rest of the buildfarm is OK. I'd work harder on this if
--disable-integer-timestamps were still a live option, but it's
hard to justify any complicated solution.

--disable-integer-timestamps ]
