eventpoll: add file based control interface

Browse source

Add do_epoll_ctl_file(), which takes a pre-resolved epoll file and a
struct epoll_filefd for the target rather than two integer file
descriptors. do_epoll_ctl() remains as a thin wrapper.

In preparation for using the file based interface from io_uring.
