dependencies: Upgrade cookie and rename Servo's Cookie to ServoCookie
This changes updates to the new version of the cookie crate in Servo
which no longer uses the old time@0.1 data types. This requires using
a new version of time while we transition off of the old one. This is
the first step in that process.
In addition, the overloading of the cookie::Cookie name was causing a
great deal of confusion, so I've renamed the Servo wrapper to
ServoCookie like we do with ServoUrl.
