stream: pipeline should use req.abort() to destroy response

[ronag]

destroy(err) on http response will propagate the error to the
request causing 'error' to be unexpectedly emitted. Furthermore,
response.destroy() unlike request.abort() does not _dump buffered
data.

Fixes a breaking change applied in 6480882.

Prefer res.req.abort() over res.destroy() until this situation is
clarified.

This is a bugfix and I believe it should be semver minor.

Fixes #31029.
