tool: Do not output libcurl source for the information only parameters

Ensure a source file isn't generated for the following informational
command line parameters when --libcurl is specified:

--help, --manual, --version and --engine list

As the output would only include a fairly empty looking main() function
and a call to curl_easy_init() and curl_easy_cleanup() when performed
with --engine list.
