sdcardCheck: shorten hardfault log availability message

[MaEtUgR]

Solved Problem

Fix expected behavior points 2. and 3. from #22259

Solution

Shorten the message
It seems to cause multiple issues to have a long message:

• The full message doesn't show on the console because the buffer only has length of log_message.text which is 127.
• The additional text shows even if the event that replaces this message already exists. I honestly didn't find the mechanism that breaks there.

Changelog Entry

Bugfix: Show hard fault log availability message correctly

Alternatives

Ideally, longer messages would be supported correctly or there would be a compile error preventing developers from using them. Note that it's not that easy because e.g. the colorized console output uses up > 50 bytes for all the WARN, coloring and module name from the 127-byte buffer.

Test coverage

• Tested the change on a pixhawk 4 and the message ending doesn't show up unexpectedly anymore.

Thanks @MaEtUgR, I was actually contemplating adding something to help catch these offenders because I find the QGC overflow handling so awful.
