    graphics/gimp-app: fix build with clang 15
    
    During an exp-run for llvm 15 (see bug 265425), it turned out that
    graphics/gimp-app failed to build with clang 15:
    
      file-dicom.c:605:26: error: incompatible pointer to integer conversion returning 'void *' from a function with result type 'gint32' (aka 'int') [-Wint-conversion]
                        return NULL;
                               ^~~~
    
    This is because the return statement is a function that should return an
    integer, not a pointer. Replace it with the error value -1, as used
    elsewhere in the function.
