ensure xml report path are relative to */pytorch/test (#60380)
Summary:
Changes the approach.
Root cause of this is for some reason: `inspect.getfile` returns absolute path instead of relative path to `os.getcwd` in newer python version. we sanitize this by removing the CI_PREFIX if applies

Test Plan:
CI
Plot twist:
windows tests are actually launched via
```
pushd test
python run_test.py
```
while linux/macos tests are
```
python test/run_test.py
```
This might cause problem when using `os.getcwd()` we will see from PR CI results.
