mpm_event: Use APR_POLLEXCL when available to prevent thundering hurd.

If APR_POLLEXCL is available, use it to prevent the thundering
herd issue. The listening sockets are potentially polled by all
the children at the same time, when new connections arrive this
avoids all of them to be woken up while most would get EAGAIN
on accept().
