Shorten messages to prevent clipping in QGroundControl

[sdomoszlai13]

Solved Problem

When I was working with QGroundControl I found that some 'Preflight Fail' messages are clipped (see e.g. attached image).

There's a 50-character limit to these messages defined by the STATUSTEXT MAVLink message. Longer messages are clipped.

In this PR, I reformulated the messages that are longer than 50 characters.

Solution

• Reformulate messages longer than 50 characters
