[PATCH bpf 2/2] selftests/bpf: add prog detach to flow_dissector test

[Stanislav Fomichev]

In case we are not running in a namespace (which we don't do by default),
let's try to detach the bpf program that we use for eth_get_headlen tests.

Fixes: 0905beec9f52 ("selftests/bpf: run flow dissector tests in skb-less mode")
