remote: force completing --mirror= instead of --mirror

"git remote --mirror" is a special case. Technically it is possible to specify --mirror without any argument. But we will get a "dangerous, deprecated!" warning in that case. This new parse-opt flag allows --git-completion-helper to always complete --mirror=, ignoring the dangerous use case.
