Remove passing ONNX logsumexp xfails (#4735)

The ONNX integration job on main reports XPASS for
ReduceLogSumExpDimIntListBoolModule_basic and
ReduceLogSumExpDimIntListIntModule_basic after logsumexp lowering landed
in #4606. Remove those tests from ONNX_XFAIL_SET so the now-passing
results are accepted. CI failure:
https://github.com/llvm/torch-mlir/actions/runs/32873854121/job/97886999091#step:10:25965.
Verification: git diff --check; Python AST parse of
projects/pt1/e2e_testing/xfail_sets.py.
