Relay: share a key combination's Meta release with frame-voice

A Meta+key combination (Meta+J for gaze_left, say) hides Meta's release
from the desktop, and the relay skipped share_key for it too. frame-voice
saw Meta go down on @frametop_keys and never come up, so it held all
dictated text back, waiting for that release. Keys of grabbed keyboards
are now shared as pressed, before key_binding() decides what the desktop
gets.
