Switch to ich777/novnc-baseimage and fix stale X lock on restart

jayfield/novnc-baseimage no longer resolves, so point at the public
ich777/novnc-baseimage instead. That image lays out TurboVNC, websockify,
and noVNC via standard package paths rather than /opt/TurboVNC and
/tmp/websockify /tmp/noVNC, so server.sh is updated to match.

Also remove any stale .X99-lock/.X11-unix socket before starting Xvnc,
since /tmp survives docker stop/start and previously left Xvnc unable to
rebind the display on restart. Signal exit-code math in signals.sh now
uses bash arithmetic instead of bc, which isn't present in the new base
image.
