While the date check is entirely bogus for the specific case of module
signing, I don't think we necessarily ought to rip it out of our generic
X.509 support entirely.

Some use cases *might* want to check the dates, and should be permitted
to do so. Just don't refuse to even *parse* the key outside its valid
date range... :)
