Non-SFI NaCl: Disallow epoll family and allow poll instead

Non-SFI NaCl: Disallow epoll family and allow poll instead

libevent tries to use epoll_create, but if it fails, it
gracefully falls back to poll and will not call other epoll
APIs. So, we return EPERM from epoll_create, allow poll, and
disallow epoll_ctl and epoll_wait.

LGTM if tests pass OK.

(Or is there a problem with tests as you mentioned on
https://codereview.chromium.org/244013002/?)
