Currently in libbpf, we have hardcoded program types that are not supported for helper function probing (e.g. tracing, ext, lsm). Due to this (and other legitimate failures), bpftool feature probe returns empty for those program type helper functions. Instead of implying to the user that there are no helper functions available for a program type, we output a message to the user explaining that helper function probing failed for that program type.
