Please review the fix for the test bug in 

ArchivedModuleCompareTest.java checks the archived system modules by 
comparing the boot layer modules from a -Xshare:off run and a -Xshare:on 
run. The -Xshare:off run in the test does not include the extra 
arguments from jtreg. Failure happens when running the test with 
"-XX:+UnlockExperimentalVMOptions -XX:+EnableJVMCI" (additional system 
modules are included in the boot layer with +EnableJVMCI). The fix is to 
use TestCommon.execOff() for the -Xshare:off process. Like 
TestCommon.exec(), TestCommon.execOff() handles the extra args from jtreg.

Tested ArchivedModuleCompareTest.java with

tier1, tier2 and tier3 via mach5.
