Resolve .local domains with getaddrinfo()

Resolve .local domains with getaddrinfo()

C-Ares doesn't go through the Name Service Switch (NSS) and thus can't
resolve certain classes of names. Generally this doesn't matter and the
whole idea of NSS is rather annoying. Nevertheless until C-Ares gets better
support, adding this hack to go through getaddrinfo() for .local domain look
up.

This reverts commit 9926dacd14c39276299712ced4a83fb043f27162.
