Subject: [PATCH] use <poll.h> instead of <sys/poll.h>

The manpage of poll(2) states that the prototype of poll is defined
in <poll.h>. Use that header file instead of <sys/poll.h> to allow
compilation against musl-libc.

Signed-off-by: Romain Naour <romain.naour@smile.fr>
(cherry picked from v1.4 branch commit 4cad505fc98240eb66eaabfae61a9694f8158dda)
