Subject: tools/bpftool: Add ringbuf map to a list of known map types
Patch-mainline: v5.8-rc3
Git-commit: c34a06c56df7c513cd19f591b26fe7d814c778cc
References: bsc#1177028

Add symbolic name "ringbuf" to map to BPF_MAP_TYPE_RINGBUF. Without this,
users will see "type 27" instead of "ringbuf" in `map show` output.
