Incorrect translator comment for ListenServerPort()?

Hi, all

When I read the ListenServerPort(), I noticed two incorrect translator
implementations: 1) the translator for setsockopt(SO_REUSEADDR), which
should not be "Unix"; 2) the translator for setsockopt(IPV6_V6ONLY),
which is applicable only to IPv6.
