libbluray: enable building bdjava
Fixes #21641 

I'm assuming optimizations were disabled for some reason, we could consider re-enabling them. @DeepwaterCreations, if you could test this out? I'd like to know if it can work without Java installed, because it currently doesn't have Java as a hard dependency.

A patch file from https://github.com/void-linux/void-packages/pull/22018.patch is attached
