switch unit/test_response.rb to Perl 5 integration test

http_response_write may benefit from API changes for Rack 3
support.

Since there's no benefit I can see from using a unit test,
switch to an integration test to avoid having to maintain the
unit test if our internal http_response_write method changes.

Of course, I can't trust tests written in Ruby since I've had to
put up with a constant stream of incompatibilities over the past
two decades :<   Perl is more widely installed than socat[1], and
nearly all the Perl I wrote 20 years ago still works
unmodified today.

[1] the rarest dependency of the Bourne shell integration tests
