public function UltimateCronBackgroundProcessLegacyLauncher::lock in Ultimate Cron 7.2

Lock job.

Background Process doesn't internally provide a unique id for the running process, so we'll have to add that ourselves. We store the unique lock id in the second callback argument.

Overrides UltimateCronLauncher::lock
