[Bug] [Fix in fork pending PR] Init script calls LSB function before including LSB functions

[tullo-x86]

Reprodutcion steps:

• On a BeagleBone Black, boot from the Debian 8.6 IoT image dated 2016-12-09.
• Login as "root", then
  adduser fab
adduser fab tty
adduser fab sudo
• Logout, then login as "fab"
• Clone OctoPrint from git
• Enter OctoPrint's directory and sudo python setup.py install
• Edit ~/OctoPrint/scripts/octoprint.default so that the user is "fab" instead of "pi"
• Set OctoPrint to start on boot:
  cd ~
sudo cp OctoPrint/scripts/octoprint.init /etc/init.d/octoprint
sudo chmod +x /etc/init.d/octoprint
sudo cp OctoPrint/scripts/octoprint.default /etc/default/octoprint
sudo update-rc.d octoprint defaults
• Try to start the service with sudo service octoprint start
• When nothing happens, check the status with sudo service octoprint status
• Note the reference to Line 31 stating that "log_warning_msg" could not be found

Expected behaviour

The init.d script should successfully start OctoPrint.

What happened instead?

The init.d script barfed because it couldn't figure out how to call "log_warning_msg" (because the line which includes it is below the call).
