Fix bug71610.phpt

Apparently example.org now rejects POST requests, so we would need to
adjust the test expectation ("Method not allowed").  However, there is
no need for an online test; instead we're just using the CLI test
server.  The serialization is a bit fiddly, but as long as there are
no quotes in `PHP_CLI_SERVER_ADDRESS` we're fine.

Closes phpGH-16063.
