[Fleet] Remove deprecated Symantec package from install_all_packages_…

…job (#193029)

## Summary

[Job](https://buildkite.com/elastic/kibana-fleet-packages/builds/1022)
`install_all_packages` is been failing for several days because of
`symantec-0.1.3` being deprecated.
Querying
```
GET kbn:/api/fleet/epm/packages?prerelease=true
```
it returns:
```
"name": "symantec",
      "title": "Symantec",
      "version": "0.1.3",
      "release": "experimental",
      "description": "Deprecated. Use a specific Symantec package instead.",
```

I'm not sure when this deprecation was announced but I'm skipping this
package from the script so the job should hopefully return green.

EDIT: package got deprecated back in 2022:
elastic/package-storage#3254
however last week we merged a
[change](https://github.com/elastic/kibana/pull/192040/files#diff-292c3f307d3d0d341a361d12416d04609a3f525be268242c2a06be06fd8d5810R188)
to temporarily remove kibana version checks when querying EPR, so this
package started appearing. In fact in previous successful runs we didn't
attempt installing this package at all.
