Server Patch: Do not remove OS from JAR name

The current server patch code removes the OS name from the file names. See [1].

This is not correct anymore and it causes an issue if the Netty dependencies need to be updated. Example:

netty-transport-native-epoll-4.1.63.Final.jar
netty-transport-native-epoll-linux-x86_64-4.1.63.Final.jar
