t5551-http-fetch: Work around some libcurl versions
Some versions of libcurl report their output when GIT_CURL_VERBOSE
is set differently than other versions do. At least one variant
(version unknown but likely pre-7.18.1) reports the POST payload to
stderr, and omits the blank line after each HTTP request/response.
We clip these lines out of the stderr output now before doing the
compare, so we aren't surprised by this trivial difference.
