    graphics/vigra: fix build with clang 19
    
    Clang 19 is more strict about manipulating `this` in C++, which results
    in an error compiling graphics/vigra:
    
        /wrkdirs/usr/ports/graphics/vigra/work/vigra-8acd73a/include/vigra/multi_iterator_coupled.hxx:493:9: error: expression is not assignable
          493 |         --this;
              |         ^ ~~~~
    
    Here, the intent is to call the prefix operator-- on the object, which
    should be spelled either "--*this" or "operator--()".
