RFR(XS): 8213151: [AIX] Some class library files are missing the Classpath exception

[Volker Simonis]

Hi,

can I please have a review for the following tiny change which fixes
the license header on a few AIX-specific files:

http://cr.openjdk.java.net/~simonis/webrevs/2018/8213151/
https://bugs.openjdk.java.net/browse/JDK-8213151

These files have been wrongly integrated (without the Classpath
Exception in their license header) from the very beginning of the AIX
port. The fix is trivial - just add the CPE to these files similar to
the corresponding sibling files.

Thank you and best regards,
Volker
