Fix incorrect includes

When compiling on Apline Linux 3.3.1, it complains:

> In file included from enter.c:30:0:
> /usr/include/wait.h:1:2: warning: #warning redirecting incorrect #include <wait.h> to <sys/wait.h> [-Wcpp]
> #warning redirecting incorrect #include <wait.h> to <sys/wait.h>

Indeed, it should be <sys/wait.h>.

Same for <sys/poll.h> in vznnc.c -- it should be <poll.h>.
