upstream: Update/replace the experimental post-quantim hybrid key exchange method based on Streamlined NTRU Prime (coupled with X25519). The previous sntrup4591761x25519-sha512@tinyssh.org method is replaced with sntrup761x25519-sha512@openssh.com. Per the authors, sntrup4591761 was replaced almost two years ago by sntrup761. The sntrup761 implementaion, like sntrup4591761 before it, is public domain code extracted from the SUPERCOP cryptography benchmark suite (https://bench.cr.yp.to/supercop.html). Thanks for Daniel J Bernstein for guidance on algorithm selection. Patch from Tobias Heider; feedback & ok markus@ and myself (note this both the updated method and the one that it replaced are disabled by default) OpenBSD-Commit-ID: 2bf582b772d81ee24e911bb6f4b2aecfd39338ae
