Revert "use plasma_install_bundled_package"
This reverts commit c505a726b3f1fff95c382e46377b495016d04786.
Quoting David Edmundson from similar commit to plasma-workspace:
"
Concept is fine, but currently we have severe CMake issues as well
as a major containment loading bug.
When re-reverting we need to be sure to test with clean install prefixes.
