Increase the number of entries set aside for zygote initiating loader lists.
The number of classes that are present when the zygote finishes
initializing increased in donut/master, above the 2000 we currently
plan for. Exceeding the limit reduces zygote sharing efficiency, so
this change raises the limit.
