Elliott Hughes 5c8c88dd8d Use the NetBSD inet_ntop until the OpenBSD bug is fixed.
Stupidly I found this bug by accident when writing the existing
tests, but I didn't think any real code would hit it. It turns
out that libcore always uses an INET6_ADDRSTRLEN-sized buffer
even when working with AF_INET addresses.
