Build PhoneBlock immediately after checkout

[SchulteDev]

This PR contains minor changes to the project build so that the build can be successfully executed locally immediately after a checkout.

1. Use of Jitpack to directly use your fix https://github.com/haumacher/java-utils-mail-dkim/tree/fix-automatic-module-name without needed extra building it locally.
2. Adjustment of the filtering of the .phoneblock file.

   - Remove global <filters> configuration that was applied during process-resources phase
   - Keep filtering in maven-war-plugin for deployment-time configuration injection
   - Allow developers to compile and test without needing environment-specific .phoneblock file
   

Fixes #202
