io_uring: flag new native workers with IORING_FEAT_NATIVE_WORKERS
A few reasons to do this:
- The naming of the manager and worker have changed. That's a user visible
change, so makes sense to flag it.
- Opening certain files that use ->signal (like /proc/self or /dev/tty)
now works, and the flag tells the application upfront that this is the
case.
- Related to the above, using signalfd will now work as well.
