Cirrus: Enable labeling of EC2 VMs

In GCP, user specified VM names are required upon creation.  Cirrus-CI
generates helpful names containing the task-ID.  Unfortunately in EC2
the VM ID's are auto-generated, and special permissions are required
to allow secondary setting of a `Name` tag.  Since this permission has
been granted, enable the `experimental` flag on EC2 tasks so that cirrus
can update VM name-tags.  This is especially useful in troubleshooting
orphaned VMs.
