Trivy analyzer can't detect SLES OS

### Current Behavior

Uploading sboms generated with trivy 0.53 for SLES 12.5 and 15.x can't be scanned by the trivy analyzer, because the OS is not detected by trivy, trivy 0.53 server log:
```
INFO Detected OS family="none" version=""
WARN Unsupported os family="none"
INFO Number of language-specific files num=0
```

### Steps to Reproduce

1. upload a trivy generated sbom with SLES 12.5 or 15.x OS packages: [trivy.json](https://github.com/user-attachments/files/16550651/trivy.json)
2. have dtrack configured to analyze with trivy
3. no OS dectected by trivy, no vulns in dtrack: [403cb7b7-81b6-4ffd-bbbb-dd910ea39249-withVulnerabilities.cdx.json](https://github.com/user-attachments/files/16550660/403cb7b7-81b6-4ffd-bbbb-dd910ea39249-withVulnerabilities.cdx.json)

### Expected Behavior

OS is set correctly by dtrack and discovered by trivy, like it does for example for redhat, and vulns are reported back to dtrack
