BamfLegacyScreen: When in Unity monitor for compiz ClientMessage's to show action menu

If we get a _COMPIZ_TOOLKIT_ACTION client message with the internal value
_COMPIZ_TOOLKIT_ACTION_WINDOW_MENU, then we are requested by compiz
to show the window action menu, and thus let's ask the proper BamfLegacyWindow
to do that, thanks to libwnck. Fixes: https://bugs.launchpad.net/bugs/1280042.

Approved by Brandon Schaefer, PS Jenkins bot.
