How to pass javatest.maxOutputSize to make test?

[Pavel Rappo]

It works, thanks!

I found a JBS issue that mentions this:
https://bugs.openjdk.org/browse/JDK-8220639. I wonder if this
parameter can be mentioned in these documents, so it could be easily
found by the next person:

  - https://openjdk.org/groups/build/doc/testing.html
  - https://github.com/openjdk/jdk/blob/master/doc/testing.md
  - https://openjdk.org/guide/#testing-the-jdk
