[JENKINS-48733] withEnv not setting PATH environment variable

With a pipeline definition similar to

```
pipeline {
agent {
docker {
image 'registry/org/buildagent'
}
}

tools {
jdk 'jdk-1.7.0_131'
maven 'maven-3.5.0'
}

stages {
stage ('Build') {
steps {
sh('mvn deploy')
}
}
}
}
```

The following message is generated

```
+ mvn deploy
/workspace/project@​tmp/durable-d723cc26/script.sh: line 2: mvn: command not found
```

This exact script works with Jenkins 2.73.1 and the Pipeline Model API 1.2.5 plugin

environment

```
Jenkins 2.89.2

Pipeline Model API 1.2.5
```

Inizia riproducendo la pipeline dichiarativa fornita con Jenkins 2.89.2, l'agente Docker e gli strumenti JDK e Maven elencati. Esamina la gestione dell'ambiente di workflow-basic-steps-plugin e confronta il risultato con la configurazione Jenkins 2.73.1 riportata; il lavoro è completo quando la pipeline riesce a risolvere ed eseguire `mvn deploy` come mostrato.
