net-misc/openssh: Version bump to 8.0_p1

- Bump the X509 patchset as well to 12.0
  - No longer apply the AES-CTR-MT with USE=X509 since it hasn't worked
    in quite some time

- Forward port the HPN patchset
  - Set the maxium number of threads in AES-CTR-MT to 16, since it
    hangs at 20 threads
