qemu: wake verb, idle stat, and no fbcon cursor in the framebuffer

- tests/qmp.py: `wake` is a judged verb (the reply must be the channel's
  own ack) and `assert_stat` knows `idle` (0 awake, 1 dimmed, 2 asleep).
  warden-ui's sleep.c swallows the touch that wakes a dimmed or blanked
  panel, so every compiled flow script now opens with wake (flare-edge
  #148); tests cover both.
- run.sh: vt.global_cursor_default=0. fbcon shares the virtio-gpu
  framebuffer with warden-ui and its cursor blinked an 8x2 block onto the
  top-left corner in some boots and not others, which made a structural
  pixel reference fail by one cell (#18). The panel has no fbcon on its
  display, so this only makes the rig match it.
