With this change, including the headers listed in resolver(3),
sys/types.h, netinet/in.h, arpa/nameser.h and resolv.h is not enough, as
resolv.h now depends on sys/time.h. This has broken at least one port,
net-mgmt/sx. It includes those 4 headers to find if the resolver library
is in libc. The test program fails like this:

In file included from conftest.c:31:
/usr/include/resolv.h:192:18: error: field has incomplete type 'struct timespec'
        struct timespec conf_mtim;      /*%< mod time of loaded resolv.conf */
                        ^
/usr/include/resolv.h:192:9: note: forward declaration of 'struct timespec'
        struct timespec conf_mtim;      /*%< mod time of loaded resolv.conf */
               ^
