Hi team,

Please review a very small fix for tests related to java/io/Serializable 
pack.

BugID: https://bugs.openjdk.java.net/browse/JDK-8169055
WebRev: http://cr.openjdk.java.net/~skovalev/8169055/webrev.00/

Issue: Several tests failing in case usage of "--limit-modules" command 
line option.
Solution: add missed declaration into test jtreg header.
