[SPARK-18190][Build][SparkR] Fix R version to not the latest in AppVeyor
## What changes were proposed in this pull request?
Currently, Spark supports the test on Windows via AppVeyor but not it seems
failing to download R 3.3.1 after R 3.3.2 is released. It downloads given R
version after checking if that is the latest or not via
http://rversions.r-pkg.org/r-release because the URL.
For example, the latest one has the URL as below:
https://cran.r-project.org/bin/windows/base/R-3.3.1-win.exe
and the old one has the URL as below.
https://cran.r-project.org/bin/windows/base/old/3.3.0/R-3.3.0-win.exe
The problem is, it seems (according to my observation, please check the
main page[1]) the versions of R on Windows are not always synced with the
latest versions.
So, it seems currently we can't download R 3.3.1 from the old repository[2]
. So, currently, AppVeyor tries to find R 3.3.1 in the old repository[2] as
3.3.2 is released but it does not exist because it seems R 3.3.2 for Windows is
not there.
Therefore, this PR proposes to lower the R version into 3.3.0 rather than
rely on the latest as SparkR supports R 3.1+ if I recall correctly.
