inet_ntop: do not compress single zeros in IPv6
maintainer's note: this change is for conformance with RFC 5952, 4.2.2, which explicitly forbids use of :: to shorten a single 16-bit 0 field when producing the canonical text representation for an IPv6 address. fixes a test failure reported by Philip Homburg, who also submitted a patch, but this fix is simpler and should produce smaller code.
