Automatically restart wrt_launchpad_daemon after install package

Automatically restart wrt_launchpad_daemon after install package

  * wrt_launchpad_daemon maintains three services:
    1. wrt_launchpad_daemon@app.service
    2. wrt_launchpad_daemon_1.socket
    3. wrt_launchpad_daemon_2.socket

[Issue#]   N/A
[Problem]  Fail to restart wrt_launchpad_daemon after install a new package,
           even though "wrt.spec" has restart command.
               - systemctl restart wrt_launchpad_daemon@app.service
[Cause]    Below preconditions are missed before restarting services.
           - "stop service" with dependency service
             (wrt_launchpad_daemon_1.socket wrt_launchpad_daemon_2.socket)
           - "daemon-reload" after installing a new service config file
           - "if" condition used wrong value.
               %post
               install ($1 == 1)
               upgrade ($1 == 2)
               uninstall (N/A) --> Only available %postun
[Solution] Fixed missed preconditions
       - "stop service" with dependency service
         (wrt_launchpad_daemon_1.socket wrt_launchpad_daemon_2.socket)
        : Add command to stop all services during running "%pre".
          Moreover, restart should do when wrt_launchpad_daemon is existed case.
          To verify condition, add condition to check "upgrade package" case.
          This change also applies to "%preun"
       - "daemon-reload" after install new service config file
        : The command for "daemon-reload" is existed in the "post". Keep current state.
          However next command is "restart service".
          As all services are stopped during running "%pre",
          it changes to "start" service only for daemon.(wrt_launchpad_daemon@app.service)
          Also add condition to run only "upgrade package" case.
