[PATCH] nss: fix build on freebsd

[Daniel P. Berrangé <berrange@xxxxxxxxxx>]

The conversion to drop gnulib in the previous patch:

  commit 8242ce4f45700f326e13e5105accd08fb4b2f0b4
  Author: Daniel P. Berrangé <berrange@xxxxxxxxxx>
  Date:   Thu Aug 8 10:23:26 2019 +0100

    tools: avoid accidentally using files from gnulib

Missed a few conversions needed for FreeBSD. In particular
netdb.h doesn't pull in sys/socket.h or netinet/in.h
