Readjust job timeouts
Readjust job timeouts

With the protection tests split out, the regular unit tests mostly
shouldn't reach the 40 minute timeout limit unless they are extremely
unlucky, so remove those overrides.

The protection tests themselves are still extremely expensive even when
split out from the rest of the tests, so bump their timeout to an hour.
