This is a follow-up fix for [JDK-8180066](https://bugs.openjdk.org/browse/JDK-8180066). As mentioned in the description of PR #1159, we should normalize the javadoc comment blocks in the `package-info.java` files, which were converted from `package.html`.
In addition to being good cleanup, it also resolves a CI test failure that was introduced by [JDK-8180066](https://bugs.openjdk.org/browse/JDK-8180066), and is being tracked by [JDK-8310654](https://bugs.openjdk.org/browse/JDK-8310654). The generated API docs are identical before and after this fix, excluding white-space changes.
