[XPU] Fix patch for old llvm package error for triton xpu (pytorch#134204)

Fixes pytorch#134199

The PR pytorch#133694 does a workaround to replace the str `"https://tritonlang.blob.core.windows.net/llvm-builds/"` with  `"https://oaitriton.blob.core.windows.net/public/llvm-builds/"` in `triton/python/setup.py`. However, in [newer version of Triton](triton-lang/triton@06e6799), it has already been changed to `"https://oaitriton.blob.core....` and don't need to be replaced.  But formerly, this will throw a runtime error.

This PR makes the `check_and_replace` logic won't fail in such a scenario. Both the old link and the newer link could work.

Also note that the `.ci/docker/common/install_triton.sh` does not need the fix, because its `sed` command won't be in effect if there is no such pattern.
