The deletion of native libraries was initially added to FileInstallArgs.cleanUpResourcesLI() as a way to get rid of old native libraries during an upgrade, but it runs well after scanPackage unpacks the new native libraries. scanPackage now removes old libraries before unpacking the new ones, so we don't need this code anymore.
