launcher-util: Initialize kb_mode also when weston-launch sets up tty

We need a valid kb_mode to restore to in case weston-launch dies and
weston has to clean up the tty.  We don't get a chance to read out the
kb mode before weston-launch changes it, but it's safe to assume that it's
always K_UNICODE.
