[SPARK-12311][CORE] Restore previous value of "os.arch" property in test suites after forcing to set specific value to "os.arch" property

Restore the original value of os.arch property after each test

Since some of tests forced to set the specific value to os.arch property, we need to set the original value.

Author: Kazuaki Ishizaki <ishizaki@jp.ibm.com>
