criu: always enable the userfaultfd support

Browse source 
Add linux/userfaultfd.h to criu sources. This header is a part
of the kernel API and I see nothing wrong to have in the repo.

Why we want to do this:
* to check that criu works correctly if a kernel doesn't
  support userfaultfd.
* to check compilation of the userfaultfd part in travis-ci.

v2: remove UFFD from FEATURES_LIST
