Restore S3 FIPS and custom endpoint capabilities

When migrating the S3 events handler to use aws-sdk-go-v2 applying
the FIPS settings and custom endpoint were inadvertently dropped.
This restores the functionality, while also adding tests to ensure
that they are always respected going forward.

A similar test was added to the dynamodb events handler as well to
prevent any regressions with FIPS settings there.
