[SPARK-56881][CORE][TESTS] Improve `FsHistoryProviderSuite` to be more
robust
### What changes were proposed in this pull request?
Skip the `SPARK-3697: ignore files that cannot be read.` test when the file
remains readable after `setReadable(false, false)` (i.e. running as `root`).
```scala
logFile2.setReadable(false, false)
assume(!logFile2.canRead, "Test requires the file to be unreadable; " +
"skipping when running as root.")
```
### Why are the changes needed?
`root` bypasses POSIX permission checks, so the test's precondition
(unreadable file) does not hold and the assertions fail. This mirrors the
existing `assume(!Utils.isWindows)` skip on the line above.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Pass the CIs.
### Was this patch authored or co-authored using generative AI tooling?
