[SPARK-34326][CORE][SQL] Fix UTs added in SPARK-31793 depending on the
length of temp path
### What changes were proposed in this pull request?
This PR proposes to fix the UTs being added in SPARK-31793, so that all
things contributing the length limit are properly accounted.
### Why are the changes needed?
The test `DataSourceScanExecRedactionSuite.SPARK-31793: FileSourceScanExec
metadata should contain limited file paths` is failing conditionally, depending
on the length of the temp directory.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Modified UTs explain the missing points, which also do the test.
Closes #31449 from HeartSaVioR/SPARK-34326-v2.
