pmbootstrap: kill process if silent for 5 minutes (rewrite logging)

Unfortunately, gitlab says in !1495 (closed):

Something went wrong while fetching comments. Please try again.

So this is the same merge request, reopened. The original comments are still here: https://github.com/postmarketOS/pmbootstrap/pull/1495

let me know if I understood correctly: the check will be performed if check=None or check=True, and only explicitly set check=False will disable it. correct?

Yes, that is correct :)

Pushed another commit with a (hopefully) better explanation.

What do you think, is this merge request ready to go?
