package/mender/S42mender: fix check-pkg and shellcheck warnings

Browse Source 
Copy the basic syntax of package/polkit/S50polkit and change the following:

  - Add DAEMON, DAEMON_PATH, PIDFILE and DAEMON_ARGS variables.
  - Fix shellcheck warning SC2166 on line 16.
  - Fix shellcheck warning SC2181 on lines 29 and 34 by assigning the return
    code from the start-stop-daemon binary to a variable, and then check the
    value of the variable.
