Subject: [PATCH bpf-next 02/11] samples: bpf: makefile: fix cookie_uid_helper_example obj build

Don't list userspace "cookie_uid_helper_example" object in list for
bpf objects.

per_socket_stats_example-opjs is used to list additional dependencies
for user space binary from hostprogs-y list. Kbuild system creates
rules for objects listed this way anyway and no need to worry about
this. Despite on it, the samples bpf uses logic that hostporgs-y are
build for userspace with includes needed for this, but "always"
target, if it's not in hostprog-y list, uses CLANG-bpf rule and is
intended to create bpf obj but not arch obj and uses only kernel
includes for that. So correct it, as it breaks cross-compiling at
least.
