buildlet: stop explicitly selecting random availability zones on EC2
This change stops explicitly selecting a random availability zone upon
EC2 vm creation if one is not set. The EC2 api will select an
availability zone with capacity for the request when an availability
zone is not set. The caller maintains the ability to set an
availability zone if needed.
