Disable OpenSSL EVP digest padding in pgcrypto
The PX layer in pgcrypto is handling digest padding on its own uniformlyfor all backend implementations. Starting with OpenSSL 3.0.0, DecryptUpdatedoesn't flush the last block in case padding is enabled so explicitlydisable it as we don't use it.This will be backpatched to all supported version once there is sufficienttesting in the buildfarm of OpenSSL 3.Reviewed-by: Peter Eisentraut, Michael PaquierDiscussion:https://postgr.es/m/FEF81714-D479-4512-839B-C769D2605F8A@yesql.se
