Removed AWS plugin from default list to fix Debian 7 build

The AWS plugin should only be added to platforms supporting the AWS SDK, but was also added to the default list, breaking the build on Debian 7. Removed from the list, so the plugin is only added is DEB_AWS_SDK is set. (cherry picked from commit defbef08fd86f0fc09f297827d6f8b952aeeace2)
