Are the Aegis Aurora unique mod "Replenishes Energy Shield by 2% of Armour when you Block" and rare shield mod "Recover x% of Life/Mana/ES when you Block" affected by the "Less Recovery" map mod?
No. The map mod gives less recovery rate, and these are instant recovery which has no rate to modify.
I believe this not entirely true. Tinkerskin has the same wording (Recover 50 Energy Shield when your Trap is triggered by an Enemy), yet if you throw traps with Eldritch Battery the Energy Shield recover IS affected by map mods. I know this because I ran out of Energy Shield way faster in maps with Less Recovery :/
That recovery is definitely not affected by any recovery rate modifiers.
