Check for Mac OS X 10.4 kqueue bug properly

Browse Source 
EV_ERROR is a bit in struct kevent::flags. Other bits may be set too.

Actually we have osx builds on travis-ci, but it uses osx 10.9.5, and we don't
have warnings there, since I guess that there is no OR'ing with previous flag
in case of error, while in 10.12 there is OR.
