WiX: revert to per-machine installs

The uninstallation path is adversely effected by the dual-purpose
builds.  This allows installation and uninstallation to function.  While
this still requires the UAC prompt, a working installation is more
important.  A subsequent change to enable per-user installs is still
feasible.
