[imports] credentials flag bits need to be updated to current fetch terminology

In http://w3c.github.io/webcomponents/spec/imports/#fetching-import the 
spec says:

   Fetch a resource from LOCATION with request's origin set to the
   origin of the master document, the mode to CORS and the omit
   credentials mode to CORS.

There is no "omit credentials" mode in the current Fetch draft, and the 
mode that _is_ there, "credentials mode", doesn't have "CORS" as a 
value.  Presumably this is asking for "same-origin"?
