Kernel: Add fast path to pselect and ppoll
...
If events are available right away, don't create epoll object to wait
on. Also fix pselect return value to the number of bits set. Previously
return value could've been greater than that if epoll return EPOLLERR or
EPOLLHUP for events that were not listened to
