More cleanup for failures on missing commands.

Currently in podman if a user specifies a command that does not exist
the tool shows the help information.  This patch changes it to show
information like:

$ ./bin/podman foobar
Error: unrecognized command 'podman foobar'
Try 'podman --help' for more information.
$ ./bin/podman volume foobar
Error: unrecognized command `podman volume foobar`
Try 'podman volume --help' for more information.
$ ./bin/podman container foobar
Error: unrecognized command `podman container foobar`
Try 'podman container --help' for more information.
