Integrate matrixbot into existing LXC 151 deploy hook

Removed standalone matrixbot/deploy.sh — deploy is handled by the existing
webhook system. Added matrixbot/ block to deploy/lxc151-hookshot.sh: on push,
if any matrixbot/ file changed, source files are synced to /opt/matrixbot and
matrixbot.service is restarted automatically.
