[jdk8u-dev] RFR: 8325927: [8u] Backport of JDK-8170552 missed part of the test

[Sergey Bylokhov]

The next line is missed in the test in the jdk8u repo:
* @requires os.family == "mac"

compare commits:
jdk: https://github.com/openjdk/jdk/commit/d12dcc701f6e51f8fa65cd36fb16a3faa7d73fe8
jdk8u: https://github.com/openjdk/jdk8u-dev/commit/bb6f0c8f500b4b4777df888bdb8a3fcf3570de5a

The test should be macOS specific since it uses the "Menlo" font.
