[PATCH net-next v2 2/2] selftests/bpf: activate the OP_NE login in range_cond()

[Menglong Dong <menglong8.dong@gmail.com>]

The edge range checking for the registers is supported by the verifier
now, so we can activate the extended login in
tools/testing/selftests/bpf/prog_tests/reg_bounds.c/range_cond() to test
such logic.
