http: fix monkey-patching of http_parser

Fixes inability to monkey-patch the HTTP Parser on Node v12.x.
This is not an issue on Node v13+ since the parser was renamed
back to the old (already monkey-patchable) `http_parser` name,
however the test in master could also use updating.

Fixes: creationix/http-parser-js#65
