selftests/bpf: Set rp_filter in test_flow_dissector
Many distributions enable rp_filter. However, the flow dissector test generates packets that have 1.1.1.1 set as (inner) source address without this address being reachable. This causes the selftest to fail. The selftests should not assume a particular initial configuration. Switch off rp_filter.
