As Kay mentioned you can stick a binary or script in
/lib/systemd/system-shutdown and it will be executed immediately before
reboot() is invoked.

Alternatively you can just write a systemd service and hook it before
shutdown.target (to run it in parallel with all other shutdown stuff) or
after shutdown.target & before final.target (to run it after the normal
shutdown but before handing things off to the binary that calls reboot()).
