Preserve extraJavaOptions ordering
For some JVM options, like `-XX:+UnlockExperimentalVMOptions` ordering is
necessary.
## What changes were proposed in this pull request?
Keep original extraJavaOptions ordering, when passing them through
environment variables inside the Docker container.
## How was this patch tested?
Ran base branch a couple of times and checked startup command in logs.
Ordering differed every time. Added sorting, ordering was consistent to what
user had in `extraJavaOptions`.
