core: Add a phony package definition 

This allows one to declare a meta-package that depends on a list
of modules. This is extremely useful for vendor provided prebulit
libraries where there is a big list of libraries/binaries to include.
Specifying that list in multiple places would be error prone and
eventually lead to very annoying bug hunts.

With a fake package, one does:

LOCAL_MODULE := my_fake_package
LOCAL_REQUIRED_MODULES := <list of required module names>
LOCAL_MODULE_TAGS := optional
include $(BUILD_PHONY_PACKAGE)
