selftests/bpf: Remove enum64 case from __arg_untrusted test suite

The enum64 type used by verifier_global_ptr_args test case requires
CONFIG_SCHED_CLASS_EXT. At the moment selftets do not depend on this
option. There are just a few enum64 types in the kernel. Instead of
tying selftests to implementation details of unrelated sub-systems,
just remove enum64 test case. Simple enums are covered and that should
be sufficient.
