S13n: port GaiaCookieManagerService to SimpleURLLoader from URLFetcher

URLFetcher will stop working with advent of Network Service, and
SimpleURLLoader is the replacement API for most clients.

Note that this only covers the code immediately here; the underlying
google_apis/gaia code is unchanged.
