PROTON-1504: epoll proactor: no PN_LISTENER_ACCEPT events if no FDs

Epoll proactor now generates PN_LISTENER_ACCEPT events only if a socket accept()
succeeds. Simplifies the code and makes it consistent with the libuv proactor.

> The libuv proactor does not generate PN_LISTENER_ACCEPT events if there are 
> no FDs available to accept the connection, i.e. if accept() returns ENFILE or 
> EMFILE. (Actually this is handled by libuv itself, the proactor code never 
> sees these errors)
> Make the epoll proactor do the same. Currently it generates 
> PN_LISTENER_ACCEPT and raises  a TRANSPORT_ERROR after the user calls 
> pn_listener_accept()
