Not sure if this "if" is necessary. It seems to me that if $cword is 4
then we are just after "id" or "file" in the command line, in which case
we hit previous cases and never reach this point?
Also, reading the completion code I wonder, do we have completion for
BTF ids? It seems to me that we have nothing proposed to complete
"bpftool btf dump id <tab>". Any chance to get that in a follow-up patch?

Same remark on the "if", I do not believe it is necessary?
