RFR: 8230374: maxOutputSize, instead of javatest.maxOutputSize, should be used in TEST.properties

[Rahul Prabhu]

Rewrote javatest.maxOutputSize as maxOutputSize in the TEST.properties file in test/jdk/jdk/lambda to match the same declarations in other TEST.properties files. The jtreg specification with the correct syntax for maxOutputSize is at https://openjdk.org/jtreg/tag-spec.html.
