MAINTAINERS: add peterx as userfaultfd reviewer

Add an entry for userfaultfd and make myself a reviewer of it, just in
case it helps people manage the cc list.

I named it MEMORY USERFAULTFD, could be a bad name, but then it can be
together with the MEMORY* entries when everything is in alphabetic order,
which is definitely a benefit.

The line may not change much on how I'd work with userfaultfd; I think
I'll do the same as before..  But maybe it still, more or less, adds some
responsibility on top, indeed.

[akpm@linux-foundation.org: add include/linux/userfaultfd_k.h, per Mike]
