Let's move this helper call from journald specific code to src/basic/, so that we can use it from sd-journal. While we are at it, slightly extend it to also cover container uids, which are also routed to the system journal now. This places the call in uid-alloc-range.[ch] which contains similar functions that match UID ranges for specific purposes.
