RFR: 8264557: Incorrect copyright year for test/micro/org/openjdk/bench/java/lang/MathBench.java after JDK-8264054

[Jie Fu]

Hi all,

The copyright year for test/micro/org/openjdk/bench/java/lang/MathBench.java [1] is incorrect since it isn't newly added in 2021.
Let's fix it.

Thanks.
Best regards,
Jie
