Don't show `Next steps:` with no messages at all when plugin returns an
unitialized value of `HookMessage` (zero-initialization sets its type to
NextSteps and empty template).

Before, for plugin commands, only the plugin name (such as `buildx`)
would be both included as `RootCmd` when passed to the hook plugin,
which isn't enough information for a plugin to decide whether to execute
a hook or not since plugins implement multiple varied commands (`buildx
build`, `buildx prune`, etc.).
This commit changes the hook logic to account for this situation, so
that the the entire configured hook is passed, i.e., if a user has a
hook configured for `buildx imagetools inspect` and the command
`docker buildx imagetools inspect alpine` is called, then the plugin
hooks will be passed `buildx imagetools inspect`.
This logic works for aliased commands too, so whether `docker build ...`
or `docker buildx build` is executed (unless Buildx is disabled) the
hook will be invoked with `buildx build`.
