kbuild: remove duplication from modules.order in sub-directories
Currently, only the top-level modules.order drops duplicated entries.
The modules.order files in sub-directories potentially contain
duplication. To list out the paths of all modules, I want to use
modules.order instead of parsing *.mod files in $(MODVERDIR).
To achieve this, I want to rip off duplication from modules.order
of external modules too.
