Get rid of unnecessary configure script tests and missing/XXX.h headers.

This also fixes configure-script problems on OSes that have IPv6 support
but don't have <netinet6/in6.h> - no standard I could find requires that
header for IPv6 support (the Single UNIX Specification speaks of
<netinet/in.h> for both IPv4 and IPv6, and RFCs 2292 and 3542 don't
mention <netinet6/in6.h>, just <netinet/in.h> and <netinet6/ip6.h>).
