Convert the "mktag" command to use parse-options.h instead of its own ad-hoc argc handling. This doesn't matter much in practice since it doesn't support any options, but removes another special-case in our codebase, and makes it easier to add options to it in the future. It does marginally improve the situation for programs that want to execute git commands in a consistent manner and e.g. always use --end-of-options. E.g. "gitaly" does that, and has a blacklist of built-ins that don't support --end-of-options. This is one less special case for it and other similar programs to support.
