make epoll_[p]wait a cancellation point

this is a Linux-specific function and not covered by POSIX's
requirements for which interfaces are cancellation points, but glibc
makes it one and existing software relies on it being one.

at some point a review for similar functions that should be made
cancellation points should be done.
