[SPARK-18875][SPARKR][DOCS] Fix R API doc generation by adding DESCRIPTION file

## What changes were proposed in this pull request?

Since Apache Spark 1.4.0, R API document page has a broken link on `DESCRIPTION file` because Jekyll plugin script doesn't copy the file. This PR aims to fix that.

- Apache Spark 2.1.0-rc2: http://people.apache.org/~pwendell/spark-releases/spark-2.1.0-rc2-docs/api/R/index.html

## How was this patch tested?

Manual.

```bash
cd docs
SKIP_SCALADOC=1 jekyll build
```
