apex: use SubName for requiredDeps

apexBundle keeps the required dependencies for native modules which are
external dependencies and then records it in .mk file as
LOCAL_REQUIRED_MODULES key.

LOCAL_REQUIRED_MODULES should list module name which are made of
cc.BaseModuleName() + SubName.

By the way, because a use_vendor:true apex is supposed to be installed
in /system/apex, we don't append SubName(.vendor) suffix.
