www/websh: report errors parsing cookie-expiration date

Original code would ignore such errors -- and would simply skip the
expiration-clause of any cookie. This MIGHT explain the test-failures
reported by Poudriere, even though I cannot reproduce this problem
locally.

Fix another minor problem, while I'm here -- and bump PORTREVISION.
