Older binaries are not deleted

[Phillipus]

Discovered by @chirontt here but perhaps better opened as an issue rather than a discussion to get more visibility.

This is since 47db2f0

The latest I-builds contain both the old and new binaries in the org.eclipse.swt.xxxx jar files.

For example: https://www.eclipse.org/downloads/download.php?file=/eclipse/updates/4.32-I-builds/I20240310-0340/plugins/org.eclipse.swt.win32.win32.x86_64_3.126.0.v20240310-0745.jar

@HannesWell : please look at this issue, I've described why it happens in #1100.

I've pushed a possible fix (#1100) but I fear that is too simple and we will miss some native libraries that aren't built yet (like https://github.com/eclipse-platform/eclipse.platform.swt/blob/d80b3268354ffc76afe1d3c2cf6cf9bb881c2c86/binaries/org.eclipse.swt.win32.win32.x86_64/WebView2Loader.dll).
