compositor-drm: reset KMS state on VT-switch in

Fix a regression with VT-switching away from Weston and then back
causing drmModePageFlip() to fail with ENOSPC or EINVAL, leaving one or
more outputs not updated. The regression appeared in
47224cc9312fef05c1a523ea0da0a1aae66f100d:

	compositor-drm: Delete drm_backend_set_modes

Fix it by forcing a drmModeSetCrtc() on all outputs both initially
created and after VT-switch in.
