This is https://bugs.debian.org/934763, which i'll work around shortly
with the attached patch to the wireguard packaging in 0.0.20190702-2.
Thanks to Jason for supplying the attached patch to update the
compatibility checks.

Note that if you apply the attached patch to wireguard and build against
4.9.168-1+deb9u5, but then try to load the module on a system running
4.9.168-1+deb9u4, the module will fail to load with unrecognized
symbols, due to the weird state of the backported siphash (but no
hsiphash).
