Minor signature change for bpf_prog_query() API, no change in behavior.
An alternative option would be to add a new libbpf introspection API
with close to 1:1 implementation of bpf_prog_query() but with changed
prog_ids pointer. Given the change is just minor enough, we went for
the first option here.
