RFR JDK-8171115: Tests containing module names ending in digits need to change

[George Triantafillou]

Please review this fix for JDK-8171115:

JBS Bug: https://bugs.openjdk.java.net/browse/JDK-8171115
Open Webrev: 
http://cr.openjdk.java.net/~gtriantafill/8171115-webrev/webrev/ 
<http://cr.openjdk.java.net/%7Egtriantafill/8171115-webrev/webrev/>

The tests were modified so that module names don't end in a digit.  The 
module tests will continue to pass regardless of when this restriction 
is enforced.

The fix was tested with the hotspot_all test group on Linux x64. Thanks.
