Node: build-docker-ubuntu1804-armv8-2

Same issue as seen here: #2137 (comment)
@smlambert exclude maybe?

[smlambert]

Yes @andrew-m-leonard, excluding makes sense until it can be addressed.

[andrew-m-leonard]

Possibly now fixed, just tried a new grinder on the same node and passes: https://ci.adoptopenjdk.net/job/Grinder/7789/console

@andrew-m-leonard safe to close?
