This is trivial, but bugged me. We should download software over HTTPS.
And we can use RAT 0.12 while at it to pick up bug fixes.

## What changes were proposed in this pull request?
This PR proposes to use https://rversions.r-pkg.org/r-release-win instead of https://rversions.r-pkg.org/r-release to check R's version for Windows correctly.
We met a syncing problem with Windows release (see #15709) before. To cut this short, it was ...
- 3.3.2 release was released but not for Windows for few hours.
- `https://rversions.r-pkg.org/r-release` returns the latest as 3.3.2 and the download link for 3.3.1 becomes `windows/base/old` by our script
- 3.3.2 release for WIndows yet
- 3.3.1 is still not in `windows/base/old` but `windows/base` as the latest
- Failed to download with `windows/base/old` link and builds were broken
I believe this problem is not only what we met. Please see 01ce943929 and also this `r-release-win` API came out between 3.3.1 and 3.3.2 (assuming to deal with this issue), please see `https://github.com/metacran/rversions.app/issues/2`.
Using this API will prevent the problem although it looks quite rare assuming from the commit logs in https://github.com/metacran/rversions.app/commits/master. After 3.3.2, both `r-release-win` and `r-release` are being updated together.

## What changes were proposed in this pull request?
It seems Hadoop libraries need winutils binaries for native libraries in the path.
It is not a problem in tests for now because we are only testing SparkR on Windows via AppVeyor but it can be a problem if we run Scala tests via AppVeyor as below:
```
- SPARK-18220: read Hive orc table with varchar column *** FAILED *** (3 seconds, 937 milliseconds)

This PR proposes to add it to the `Path` for AppVeyor tests.
