debug: Add cli_argv field to monolog WikiProcessor

Follows investigation from T172559, where we found that there is no explicit
way to find what script triggered particular error messages when the script
was run from the command-line (as opposed to a web request, where the
built-in WebProcessor adds fields like http_method and url).
