Move the future back by 19 years.

The following cookie lifetime tests prophesied that 8am GMT 7th Aug 2019
would never arrive, but in hindsight this prediction turned out to be
overly pessimistic, as evidenced by the tests failing across the board:

  external/wpt/cookies/http-state/comma-tests.html
  external/wpt/cookies/http-state/general-tests.html
  virtual/samesite-by-default-cookies/external/wpt/cookies/http-state/comma-tests.html
  virtual/samesite-by-default-cookies/external/wpt/cookies/http-state/general-tests.html

This CL redefines the future as the very first second of the year 2038,
which is admittedly a couple of days earlier than when the world will
actually end, but is hopefully a good enough approximation as it seems
unlikely that in those final days it will be anybody's primary concern
that these tests are failing.
