RFR 8036104: Rename the PAData.java test

[Wang Weijun]

Please review the fix for

   https://bugs.openjdk.java.net/browse/JDK-8036104

Basically, the PAData.java test has the same name as the internal PAData.java 
source file. IntelliJ IDEA always shows me the code completion hints I do not 
want. And when I manually code the correct method, it shows an red flag.

This is a trivial change and no webrev.

diff --git a/test/sun/security/krb5/PAData.java 
b/test/sun/security/krb5/TestPAData.java
rename from test/sun/security/krb5/PAData.java
