fix system app's abi error after uninstall updated version.

Browse Source 
When uninstall an updated system app, we always did as
following steps. First we delete data structure by calling
deleteInstalledPackageLIF(), then enable it from disabled
system packages and re-adding to PackageSettings map by
calling addPackageLPw(). At last re-installing apps in
system partition with scanPackageTracedLI().

But if an package with sharedUserId readded failed with
exception of 'Adding duplicate shared id: xxx', then we
cann't reuse it's derived CPU Abis from settings, others
we could get CPU Abis uninitialized errors.

Test: Manual; Update an system app with sharedUserId
Test: Manual; Uninstall and ensure it run ok
