  rest_client: Fix a rest_post() regression bug

Commit c549e6ec added an unnecessary libcurl option which caused
the HTTP headers to be logged into the output body pseudo-variable
alongside the request body when performing a rest_post().

This patch disables the above-mentioned libcurl option (CURLOPT_HEADER).

Reported by @goharahmed on GitHub.
Fixes #1247.
