[PATCH 4/7] nfs-utils: Add dependency for getaddrinfo(3) in configure.ac

[Chuck Lever <chuck.lever@oracle.com>]

Lots of parts of nfs-utils already depend on getaddrinfo(3).

We could find each instance where getaddrinfo(3) is invoked, wrap it with
#ifdef HAVE_GETADDRINFO, and provide equivalent logic without it, but that's
a whole lot of work... and no-one has complained about this so far.

So as a clean-up, let's simply add a hard dependency for it in configure.ac,
and call it a day.
