fix usage string for the kubectl logs command

Even though the use of an inline [CONTAINER] name is still accepted for,
legacy purpose the error message does not match what the documentation
or man page says. This commit aligns the usage string that is displayed
when the `kubectl logs` command is called with more than one container
name (with the use of the -c flag or not).
