RFR (S): 8213233: [TESTBUG] re-evaluate test/hotspot/jtreg/runtime/JVMDoPrivileged tests following JDK-8212605

[David Holmes]

Hi Security-libs team,

webrev: http://cr.openjdk.java.net/~dholmes/8213233/webrev/
bug: https://bugs.openjdk.java.net/browse/JDK-8213233

Now that doPrivileged is Java-based these older runtime regression tests 
don't really belong in runtime any longer. I'd like to hg move them to 
test/jdk/java/security/AccessController

Thanks,
David
