Fix package import issue in state-machine-*.l

[mqcmd196]

In state-machine-utils.l, state-machine-inspector class is initialized. However, it is in state-machine-ros.l.

Without this PR, when I use exec-state-machine function, the error occurs like

This PR fixes it to load state-machine-ros.l in state-machine-utils.l
