New issue by ericonr on void-packages repository

https://github.com/void-linux/void-packages/issues/25534

Description:
### Expected behavior

Building a package with xbps-src doesn't add multiple entries to syslog, so `svlogtail xbps` only includes entries run on the actual system.

### Actual behavior

Building a package with xbps-src adds multiple entries to syslog, unnecessarily polluting `svlogtail xbps` output.

---

I'm not sure what the correct place for fixing this is? Perhaps a flag for XBPS to not store info in syslog.
