[13u] RFR: 8248406: Some zipfs tests fail with AccessControlException

[Andrew Brygin]

Hello,

 could you please review a fix for JDK-8248406?

Webrev: http://cr.openjdk.java.net/~bae/13u/8248406/webrev.00/

 This is a regression in 13.0.4 caused by an incomplete backport of
JDK-8229888:
 https://hg.openjdk.java.net/jdk-updates/jdk13u/rev/cabda0c85f17

 Following tests fail in 13.0.4 with AccessControlException:

  jdk/nio/zipfs/DirectoryStreamTests.java
  jdk/nio/zipfs/ZFSTests.java
  jdk/nio/zipfs/ZipFSTester.java

 The root cause of the failure is that default.policy has not been
updated with RuntimePermission "accessUserInformation". In jdk14 this
update was a part of the fix for JDK-8213031. This fix has not been
backported to 13u, so this permission update shall be done as a part of
backport for JDK-8229888, but it has been missed.

 Suggested solution is to add RuntimePermission "accessUserInformation",
as it was done in 11u as a part of the backport of JDK-8229888:

https://hg.openjdk.java.net/jdk-updates/jdk11u-dev/rev/57fd597352b8#l1.7

Thanks,
Andrew
