ruby: fix non-IPv6 support

When IPv6 support is disabled, this recipe mis-configures
ruby so that it end up non-working:
--enable-wide-getaddrinfo instructs ruby to re-implement
the standard getaddinfo(), but IPv6 support is still
automatically detected via ext/socket/extconf.rb
independently of that flag.

To re-implement getaddrinfo(), ruby uses the obsolete
getipnodebyaddr() and getipnodebyname() functions - i.e.
according to the man-page, glibc provided those only in
glibc 2.1.91-95; and of course compilation fails. [1]

Switch to ruby's standard --enable-ipv6= configure
options to make the build work without warnings, and
ruby work at runtime as well.

[1] Compilation and linking actually succeed, albeit with
a warning regarding implicit declaration / unresolved
symbols. The error is only obvious at runtime due to the
unresolved symbols...
