On 32-bit machines, cookies with expiration dates beyond the year 2037
are stored with the expiration time as base::Time::Max(). When
converting to a double, this will return infinity(). infinity() cannot
be serialized in JSON, which can lead to a crash.

Instead, gracefully handle this case by setting the cookie to expire at
std::numeric_limits<double>::max(). Add a regression test for the same.
