parse-options: introduce OPT_IPVERSION()
The command line option parsing for "git clone", "git fetch", and
"git push" have duplicated implementations of parsing "--ipv4" and
"--ipv6" options, by having two OPT_SET_INT() for "ipv4" and "ipv6".
Introduce a new OPT_IPVERSION() macro and use it in these three
commands.
