[SPARK-22344][SPARKR] Set java.io.tmpdir for SparkR tests

This PR sets the java.io.tmpdir for CRAN checks and also disables the hsperfdata for the JVM when running CRAN checks. Together this prevents files from being left behind in `/tmp`

## How was this patch tested?
Tested manually on a clean EC2 machine

Author: Shivaram Venkataraman <shivaram@cs.berkeley.edu>

Closes apache#19589 from shivaram/sparkr-tmpdir-clean.
