Remove ServerTokens from apache configurations

[MrGeneration]

Infos:

• Used Zammad version: Zammad 3.5 and earlier
• Installation method (source, package, ..): any but hosted
• Operating system: any
• Database + version: any
• Elasticsearch version: any
• Browser + version: any

Expected behavior:

Apache2 starts without issues using the default http configuration files.

Actual behavior:

Apache2 can't start, because ServerTokens is no valid setting within the VirtualHost section.
