Set CPU Abis for updated system packages

Symptom:
If Chrome package is updated and is disabled after reboot, all apps are
crashed when they use WebView.

Root cause:
CPU Abis for updated system packages are not set when newer version
exist. Updated system packages are not fully scanned.
But WebView can use WebViewProvider in the system Chrome package. It
refers CPU Abis and crash happens.

Solution:
Set CPU Abis even if the system package has newer updated version.
