Subject: [PATCH] test: http complete list of non-concat headers

The original test was only testing some of the headers that shouldn't be
concatenated as per lib/_http_incoming.js, so now the full list is
there.

'content-length` gives a parse error if you set it to a string, so the
test for that header uses numbers.
