  stir_shaken: Fix detection for invalid "future Date/iat"

This patch fixes a bug where both the Date hf and the "iat" PASSporT
claim could be filled in with a random timestamp value "in the future"
and still bypass the OpenSIPS "freshness" integrity checks.

Issue discovered during OpenSIPIt'03,
        thanks to Pavel Bussel & Maksym Sobolyev (Sippy Software)
