CertificateTest: explicitly set validity check date

Since this test uses pre-generated certificates, they will expire
eventually given enough time. Instead of regenerating them, just set the
date in the PKIXParameters to compare their validity against.

(cherry picked from commit 4412830e6a850acf830fda4dbdc3e5da7950c87b)
