RFR: JDK-8174895: test/TestCommon.gmk: value of JTREG_TESTVM_MEMORY_OPTION is missing1/2acghpy

[Erik Joelsson]

There is a small bug in the new test/TestCommon.gmk that prevents the 
JTREG_TESTVM_MEMORY_OPTION from propagating to the jtreg command line. 
The fix is to append to JTREG_TEST_OPTIONS instead of overwriting the 
current value further down in the file. Patch provided by Amy Lu.
