awslogs: Update aws-sdk-go to support IMDSv2
AWS recently launched a new version of the EC2 Instance Metadata
Service, which is used to provide credentials to the awslogs driver when
running on Amazon EC2.  This new version of the IMDS adds
defense-in-depth mechanisms against open firewalls, reverse proxies, and
SSRF vulnerabilities and is generally an improvement over the previous
version.  An updated version of the AWS SDK is able to handle the both
the previous version and the new version of the IMDS and functions when
either is enabled.

More information about IMDSv2 is available at the following links:

* https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/configuring-instance-metadata-service.html

Closes https://github.com/moby/moby/issues/40422
