GH-218: Fix logging for AbstMesAttrsHeaderMapper

Fixes #218

The `AbstractMessageAttributesHeaderMapper` incorrectly logs only for
SQS service.

* Fix `logger` property to be a `protected` and not `static` to make it
rely on the `getClass()` context
* Fix logging message in the `fromHeaders()` from just `SQS` to `the current AWS service`

**Cherry-pick to `2.5.x`**
