LOG_TAG is missing in SystemD Journal

[b2ag]

Describe the bug
Snapserver produces log lines like
2024-08-21 18-33-03.633 [Info] (Snapserver) Version 0.28.0
where Info denotes the severity (or level or priority) and Snapserver is the LOG_TAG.

Unfortunately the LOG_TAG information is not printed to the journal when Snapserver runs deamonized (and uses syslog to log messages I guess).

LOG_TAG should also be available to SystemD JournalD.

Steps to Reproduce

1. Run Snapserver without --daemon and look for the LOG_TAG.
2. Run Snapserver with --daemon and look again for the LOG_TAG.

Environment details

• OS: NixOS
• Snapcast version 0.28.0
