Minor clightning fixes

[erikarvstedt]

Use this to test commit clightning: don't cleanup socket on startup:

read -rd '' script <<'EOF' || :
  systemctl stop clightning
  echo
  echo 'clightning has stopped'
  systemctl status clightning | head -3
  echo
  echo 'the socket still exists after clightning has stopped'
  ls /var/lib/clightning/bitcoin/lightning-rpc
  echo
  systemctl start clightning
  echo 'clightning starts, rpc calls work'
  sleep 0.5
  lightning-cli getinfo
EOF
run-tests.sh -s clightning container --run c bash -c "$script"
