eventpoll.h: add missing epoll event masks

Browse Source 
[resend due to me forgetting to cc: linux-api the first time around I
posted these back on Feb 23]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

For some reason these values are not in the uapi header file, so any
libc has to define it themselves.  To prevent them from needing to do
this, just have the kernel provide the correct values.
