RFR(s): 8165870: Fix module dependencies for javax.script/* tests

[Sergei Kovalev]

Hello team,

Could you please review small fix for javax.script tests.

Bug ID: https://bugs.openjdk.java.net/browse/JDK-8165870
Webrev: http://cr.openjdk.java.net/~skovalev/8165870/webrev.00/

Root cause: Some tests failed in case no required module exists in JVM.
Summary: adding '@modules' jtreg tag to skip tests that cannot be 
executed if module not exists.
The fix tested locally using JTreg test suite.

With best regards,
Sergei
