device-purim-librem5: Unload/reload bluetooth firmware before/after suspend (systemd variant)

Browse source 
Fixes bluetooth not being available on resume. The script was adapted from mobian and adjusted to reload the firmware in a non-blocking fashion in the background.

In some (rare) cases it fails and entering suspend, waiting 10 seconds and waking up is required. Yet this is a huge improvement over not having bluetooth after sleep at all until the next reboot.

[ci:skip-grep] to avoid failures due to ongoing treewide changes
