OPTIM: epoll: make use of EPOLLRDHUP

epoll may report pending shutdowns using EPOLLRDHUP. Since this
flag is missing from a number of libcs despite being available
since kernel 2.6.17, let's define it ourselves.

Doing so saves one syscall by allow us to avoid the read()==0 when
the server closes with the respose.
