Adjust 'gfortran.dg/goacc/privatization-1-*' [PR103576, PR103697]

... for the recent commit 494ebfa7c9aacaeb6ec1fccc47a0e49f31eb2bb8
"Fortran: Handle compare in OpenMP atomic", which changes the GIMPLE IR
such that a temporary is no longer used; 'original' dump:

             x = *a;
    -        {
    -          integer(kind=4) D.4237;
    -
    -          D.4237 = *a;
               #pragma omp atomic relaxed
    -            &y = D.4237;
    -        }
    +          &y = *a;
           }

(I'm not familiar to comment whether that's correct; but it appears that the
difference again disappears in later compiler passes.)

These OpenACC test cases verify behavior re OpenACC privatization levels, and
have to be adjusted accordingly.
