Subject: [PATCH] configure,rbldnsd.c: include <poll.h> instead of
 <sys/poll.h>.

As far back as 1997, the Single UNIX Specification (that later became
POSIX) has said that <poll.h> is the file that provides poll() and
friends:

  https://pubs.opengroup.org/onlinepubs/7908799/xsh/poll.h.html

Most implementations also support the old <sys/poll.h>, but musl, for
example, raises a warning about its usage:

  https://git.musl-libc.org/cgit/musl/tree/include/sys/poll.h

This commit updates <sys/poll.h> to <poll.h> in two places.

Closes: https://github.com/spamhaus/rbldnsd/issues/25
