NodePlugin runs uname twice

[adam-enko]

NodePlugin runs uname twice:

• Once on line 90 (the result is unused)

  https://github.com/node-gradle/gradle-node-plugin/blob/7.1.0/src/main/kotlin/com/github/gradle/node/NodePlugin.kt#L90-L94

• Again on lines 91-94

  https://github.com/node-gradle/gradle-node-plugin/blob/7.1.0/src/main/kotlin/com/github/gradle/node/NodePlugin.kt#L91-L94

Perhaps this is intentional, but I just wanted to double check, in case it was a mistake. If it's intentional I think it would help to add a comment to explain the purpose.

It's a mistake that snuck in with a refactor, good catch!
