Track rename of org.kxml to com.android.org.kxml

Update preloaded-classes to track libcore class renames.

The class renames may have caused a regression in some
performance metrics, though overall boot time was unaffected.
This is probably because the first user is now paying the cost
of the class initialization and that happens to be in the affected
metrics. There's no reason not to update the preloaded-classes.

Metrics affected:
SystemServerTiming_StartUsageService_avg
SystemServerTiming_StartJobScheduler_avg
SystemServerTiming_StartJobScheduler_avg

Test: build only
