Threads do not clean terminate on exit signals

[elschnorro77]

• close_script() does not wait for threads to end prior to sys.exit()
• "systemctl stop | restart honeypi.service" not catched at all

Are there any threads that cause a real issue?
I observed in main.py there is ttimesync and tgpstimesync, but there are also other short term lived threats such as for the button press detection or the led blinking.

I would only focus on those which lead to a irreversible state of the service or break something.
