kbuild: make clean rule robust against too long argument error
Commit cd968b97c492 ("kbuild: make built-in.a rule robust against too
long argument error") made a build rule robust against "Argument list
too long" error.
Eugeniu Rosca reported the same error occurred when cleaning an external
module.
The $(obj)/ prefix can be a very long path for external modules.
Apply a similar solution to 'make clean'.
