util/userfaultfd: Remove unused uffd_poll_events

uffd_poll_events has been unused since it was added; it's also
just a wrapper around a plain old poll call, so doesn't add anything.

migration: Clean up includes

This commit was created with scripts/clean-includes.

All .c should include qemu/osdep.h first. The script performs three
related cleanups:

* Ensure .c files include qemu/osdep.h first.
* Including it in a .h is redundant, since the .c already includes
it. Drop such inclusions.
* Likewise, including headers qemu/osdep.h includes is redundant.
Drop these, too.
