[PATCH bpf-next v1 5/8] resolve_btfids: Fix the _impl lookup for module BTF

[Ihor Solodrai <ihor.solodrai@linux.dev>]

process_kfunc_with_implicit_args() skips generating <name>_impl
function when one already exists for backwards compatibility.

It uses btf__find_by_name_kind(), which searches the base BTF before
the split BTF. When resolve_btfids processes a module, a same-named
_impl in vmlinux would be found and the module's own counterpart would
not be created.

Fix by using btf__find_by_name_kind_own() for the lookup.
