[tests] skip core-dump test on xpu

[faaany]

Summary

Some tests cause a core dump on XPU. We are fixing this. But for now, let's skip it for XPU CI.

Below are the test results with "make test" on XPU after the skip:

======================================================== 738 passed, 223 skipped, 42 warnings in 70.34s (0:01:10) =========================================================

• Hardware Type: Intel(R) Data Center GPU Max 1550
• run make test to ensure correctness
• run make checkstyle to ensure code style
• run make test-convergence to ensure convergence
