event: allow EPOLLET as event flag
EPOLLET enables edge-triggered mode (see epoll(7) for more). For most
use-cases, level-triggered is just fine, but for master-TTYs we need
edge-triggered to catch EPOLLHUP. master-TTYs signal EPOLLHUP if no client
is connected, but a client may connect some time later (same happens
during vhangup(2)).
However, epoll doesn't allow masking EPOLLHUP so it's signaled constantly.
To avoid this, edge-triggered mode is needed.
