configure.in fix (netbsd-current) for 2.1.0p3

[itojun at iijlab.net]

	thanks for great package.  configure.in shipped with 2.1.0p3 includes
	too few header files for detecting struct sockaddr_in6 and in6_addr,
	and the build will fail on netbsd-current (1.4Z).  here's a
	tiny patch to make the build successful.
