springbootdemo: fix antrun phase and .mar overwrite for reliable builds

Two related fixes:
- Move antrun execution from 'install' to 'prepare-package' phase so that
  'mvn package' (not just 'mvn install') assembles the .aar services, copies
  axis2.xml, and creates the openapi .mar — the previous binding meant a
  'mvn package -DskipTests' silently produced a stale deployment directory
- Add overwrite="true" to both .mar copy tasks so a pre-existing .mar from
  a previous build is always replaced with the latest jar from .m2/repository

Applied to both springbootdemo (WildFly) and springbootdemo-tomcat11.
