[PATCH net-next 4/8] tools: bpftool: add `bpftool prog help` as real command i.r.t exit code

[Jakub Kicinski]

From: Quentin Monnet <quentin.mon...@netronome.com>

Make error messages and return codes more consistent. Specifically, make
`bpftool prog help` a real command, instead of printing usage by default
for a non-recognized "help" command. Output is the same, but this makes
bpftool return with a success value instead of an error.
