[PATCH 3/5] reflect changes in Rack::Utils::HTTP_STATUS_CODES

[Eric Wong <e@80x24.org>]

Applications may want to alter the message associated with HTTP
status codes in Rack::Utils::HTTP_STATUS_CODES.  Avoid memoizing
status lines ahead-of-time

Note: this introduces a minor performance regression, but ought to
be unnoticeable unless you're running "Hello world"-type apps.
