Java Security Provider unsupported for SslProvider: OPENSSL

[illustris]

Description of the bug

Skein does not work on distros with newer versions of packages.
I first encountered this issue on NIxOS, but I've also reproduced the issue on arch. See below for repro steps.

I'm not entirely sure what causes this issue, but I suspect it has something to do with openssl. I found that the following patch fixes the issue:
