libbpf: Export btf__find_by_name_kind_own()

Browse Source 
btf__find_by_name_kind() searches the base BTF before the split BTF,
so in case of a name collision between base and split it always
returns a base type. Tools that process split BTF may need to restrict
a lookup to the split's own types.

The internal helper btf__find_by_name_kind_own() already does exactly
that. Make it a public API.
