LU-6401 lustre: make lustre_user.h compile in user space

While building my own lustre dependent application on
Ubuntu I discovered that lustre_user.h does not compile
due to libcfs/types.h not being packaged. So instead of
fixing the packaging just remove the libcfs/type.h
dependency from lustre_user.h which needs to be done
anyways.
