Fix arm disarm button notification color

Fix the Flight Data arm/disarm GUI button and menu option for arm/disarm to display the correct value.

Due to logic code that was put in the opposite section to what it should have been the buttons displayed the opposite of what the correct status should have been.

Now they both display Disarm as the option when the vehicle is armed and Arm when the vehicle is disarmed.

GUI button also displays the correct colors now.

The revert commit is to get rid of sysid changes that shouldn't appear in this branch/pull.
