CHROMIUM: kbuild: clang: Disable the 'duplicate-decl-specifier' warning

Browse source 
clang generates plenty of these warnings in different parts of the code.
They are mostly caused by container_of() and other macros which declare
a "const <type> *" variable for their internal use which triggers a
"duplicate 'const' specifier" warning if the <type> is already const
qualified.
