[aarch64-port-dev ] RFR(XXS):8248570 Incorrect copyright header in TestUnsafeUnalignedSwap.java

[Wang Zhuo(Zhuoren)]

Hi,
There's something wrong int the legal notice of TestUnsafeUnalignedSwap.java file. It should be GPLv2 as in `make/templates/gpl-header`. This patch(from Vladimir Kozlov) fixes it.
