logind: forward Active=true changes for non-DRM backends

Logind sends us a notification whenever the Active attribute of our session
changes. However, due to the way compositor-drm.c relies on the master DRM
device to be synced with the session, we used to delay Active=true
handling until the DRM device was up, too. See:

        logind: delay wakeup until DRM-device is resumed

However, the other compositor backends do not use DRM, so logind-util will
never get notified about any DRM device. Therefore, we have to forward the
Active=true change immediately.

This commit fixes logind-util to take sync_drm as argument. If it is true,
we do DRM-device synchronisation, otherwise we don't.
