RFR: 8165687: Fix license and copyright headers in jd9 under hotspot/test

[Stanislav Smirnov]

Hi,

Please review this fix for JDK-8165687 <https://bugs.openjdk.java.net/browse/JDK-8165687>.
Legal notices and Oracle copyrights were updated (white and blank space, commas) in tests files for uniformity to meet Oracle requirements.
