sql/cdc: TestChangefeedRandomExpressions/kafka error: cannot subtract infinite dates

[rharding6373]

Original error: https://teamcity.cockroachdb.com/viewLog.html?buildId=12496837&buildTypeId=Cockroach_BazelEssentialCi&tab=buildResultsDiv

Here's a reduced repro (no artifacts in the build):

CREATE TABLE seed (_date DATE, _inet INET);
INSERT INTO seed VALUES ('infinity'::DATE, '0.0.0.0'::INET);
CREATE CHANGEFEED WITH schema_change_policy='stop' AS SELECT rowid FROM seed WHERE (set_masklen(seed._inet::INET, (seed._date::DATE - seed._date::DATE)::INT8::INT8)::INET = seed._inet);

-- Note that the following statement without changefeed doesn't error, because the subtraction is optimized out of the plan.
SELECT rowid FROM seed WHERE (set_masklen(seed._inet::INET, (seed._date::DATE - seed._date::DATE)::INT8::INT8)::INET = seed._inet);

I would either expect 1) The subtraction can be removed from the changefeed plan, or 2) The randomized test can tolerate such failures.
