I don't think all of them. Only --mapcompat and --bpffs. bpffs could
be argued. On mapcompat I must have not read the patch fully, I was
under the impression its a global libbpf flag :(
--json, --pretty, --nomount, --debug are global because they affect
global behaviour of bpftool. The difference here is that we basically
add a syscall parameter as a global option.
