tool: Fixed libcurl source output for multiple operations

Correctly output libcurl source code that includes multiply operations
as specified by --next. Note that each operation evaluates to a single
curl_easy_perform() in source code form.

Also note that the output could be optimised a little so global config
options are only output once rather than per operation as is presently
the case.
