Deb: Remove unmaintained AWS key plugin packaging

Likewise to TokuDB and Cassandra, if this plugin is maintained it should
be either fully enabled or not present at all. Packaging can be recovered
from MariaDB 10.2 if needed, or if build outside of this packaging, then
also the packaging scripts and snippets should be injected from the
outside.
