Subject: don't print help message for usage errors

Don't print potentially verbose help messages in case of usage errors,
but print only the usage error followed by a pointer to the command's
help.  This aligns with Docker.

```
$ podman run -h
flag needs an argument: -h
See 'podman run --help'.
```
