Prevent system app upgrading from multi-arch to single-arch

Prevent system app upgrading from multi-arch to single-arch

We should not let user to manully upgrade a system app which supports
multi-arch to a newer version which supports only one cpu abi. Take
webview as an example, if the user upgraded the webview to a version
supports only armeabi-v7a on Nexus 5X by mistake, then any app supports
only arm64-v8a and uses webview to display web contents would not work
properly then as loading a 32bit native lib inside a 64bit mode process
is not allowed.
