RFR: 8161208: Unable to run jtreg tests with MinimalVM

[Michail Chernov]

Hi,

Could I have a reviews for this change, please?

https://bugs.openjdk.java.net/browse/JDK-8161208
http://cr.openjdk.java.net/~mchernov/8161208/webrev.00/
http://cr.openjdk.java.net/~mchernov/8161208/webrev.hotspot.00/

This issue is started since this fix:
http://mail.openjdk.java.net/pipermail/hotspot-gc-dev/2016-June/018319.html

This change fixes two issues:
1. Avoiding of java.management usage with minimal VM (JTreg was started 
with '-vmoptions:"-minimal"' and worked as expected).
2. Adding appropriate modules for proper VMProps execution on non-full 
JDK images (JTreg was tested with '-vmoptions:"-limitmods java.base"', 
java.compact1, java.compact2 and so on - JTreg is started and works as 
expected).

Tested locally and via RBT/JPRT.

Thanks
Michail
