QT_ANDROID_PACKAGE_SOURCE_DIR not working

QT_ANDROID_PACKAGE_SOURCE_DIR CMake property is not working, any custom Android templates from the source directory are ignored and the "android-package-source-directory" entry is missing from the deployment.json file.

Steps to reproduce:

• pull qtbase latest dev (sha of lates commit at the time of writing d09a9f6de3cf672e52fd4081eec7b07b9ed0e877 )
• build & install
• add custom Android templates, e.g. following the directions here
• optionally modify some of the added templates to verify their content is overwritten
• build the app for Android
• check the deployment-settings.json from the app's build directory
  • expected: it should have an "android-package-source-directory" entry with the value of the added Android source directory
  • actual: no entry for ""android-package-source-directory" is found
• if you modified the added custom templates, check their content from under <app-build-dir>/android-build - the modifications are overwritten with the default templates
