Output: Fix unnamed enum value references in default arguments

In code like

    namespace ns {
      enum { E = 0 };
      void f(int = E);
    }

we use `clang::NamedDecl::printQualifiedName` to print the fully
qualified name of the enum constant `E`.  However, the method produces
`ns::::E` when the enumeration type itself is not named.  Work around
this problem by removing one of the `::` from the result.
