Remove hashtree from builtin APEXes
Builtin APEXes (/system, ...) don't need hashtree.
So if we remove hashtree from builtin APEXes we can save more space in
/system.
However, this change only affects to the apex bundles which are built
from source, not from prebuilts.
Removing hashtree from prebuilts will be handled in a follow CL.
