Subject: [PATCH] main: Set a shorter stale time for the lock file

This is especially important for the Flatpak version which always uses
the same PID. So in case of an unclean shutdown, the stale time is used
to check if the lock file is still valid.
It was incorrectly set to never be stale. So let's set it to 10000
milliseconds.

Fixes #771.
