Use official CentOS & Ubuntu images via prodId
The previous filter method could result in getting an unexpected image
even one that's entirely different than what is intended. This patch
uses a product-code search of the marketplace for the official upstream
supported images rather than the custom ones provided by Amazon.
This patch is based on Zack William's suggestion on the lf-releng
mailinglist.
