fixup! ERP5/zopewsgi: Add option to set soft limit of open file descriptors to hard limit

In nexedi/erp5@39369169 the new option
'nofile' was added to set the soft limit of open file descriptors to its hard limit.
In nexedi/slapos!1451 (comment 193296) it was criticized that
the name of the option - 'nofile' - is too vague and in nexedi/slapos!1465 a new
name for the option was searched. Finally we agreed on the more explicit 'with-max-rlimit-nofile'.
