If we keep the $enabled != "no" logic all the way through, $enabled,
unless explicitly turned off or missing dependencies, will be
undefined when the configure options are summarized via:

  configure: qemu-ga: report MSI install support in summary

requiring the user to infer whether we'll default to "yes" or "no".
The current logic in fact defaults to "yes" in function, so with this
patch we're simply setting that flag early on so we can report "yes"
rather than undefined.
