Fix syntax for cloudtrail_org s3 and lambda lists

[andersem]

When running the sra-easy-setup with the CloudTrail solution, and these parameters set:

- parameter_key: pEnableLambdaDataEvents
  parameter_value: "true"
- parameter_key: pEnableS3DataEvents
  parameter_value: "true"

the CloudTrail stack creation fails with this error:

This Custom::LambdaCustomResource resource is in a CREATE_FAILED state.

Received response status [FAILED] from custom resource. Message returned: An error occurred (InvalidEventSelectorsException) when calling the PutEventSelectors operation: Value arn:aws:s3:::* for DataResources.Values is invalid.

and:

Received response status [FAILED] from custom resource. Message returned: An error occurred (InvalidEventSelectorsException) when calling the PutEventSelectors operation: Value arn:aws:lambda:* for DataResources.Values is invalid.

Fixing this by correcting the syntax.
