RFR(XS): 8176403: [TESTBUG] gc/arguments/TestSmallInitialHeapWithLargePageAndNUMA is referencing no longer existing group

[sangheon]

Hi all,

Could I have some reviews for this change?

As current TestSmallInitialHeapWithLargePageAndNUMA.java uses old test 
group tag, changed to use the new tag.

The test uses the old test group tag but it is not tested on JPRT. 
Because recently jprt.properties file was changed and I was using the 
old one.

CR: https://bugs.openjdk.java.net/browse/JDK-8176403
webrev: http://cr.openjdk.java.net/~sangheki/8176403/webrev.0
Testing: JPRT (checked the test is ran and passed)

Thanks,
Sangheon
