Lorenz Bauer f9b7ff0d7f tools/bpftool: Fix attaching flow dissector 
My earlier patch to reject non-zero arguments to flow dissector attach
broke attaching via bpftool. Instead of 0 it uses -1 for target_fd.
Fix this by passing a zero argument when attaching the flow dissector.

Fixes: 1b514239e8 ("bpf: flow_dissector: Check value of unused flags to BPF_PROG_ATTACH")
