bpftool: remove support of --legacy option for bpftool
Following:
commit bd054102a8c7 ("libbpf: enforce strict libbpf 1.0 behaviors")
commit 93b8952d223a ("libbpf: deprecate legacy BPF map definitions")
The --legacy option is no longer relevant as libbpf no longer supports
it. libbpf_set_strict_mode() is a no-op operation.
