[PATCH bpf-next] selftests/bpf: rename reference_tracking BPF programs

[Andrii Nakryiko]

BPF programs for reference_tracking selftest use "fail_" prefix to notify that
they are expected to fail. This is really confusing and inconvenient when
trying to grep through test_progs output to find *actually* failed tests. So
rename the prefix from "fail_" to "err_".
