patch to add support for changed struct on 1400066 and newer

Since OSVERSION 1400066, one get the following breakage when try to build
net/wireguard on CURRENT:

Since commit e7d02be, the struct pr_usrreqs is merged into struct protosw. The
attached patch uses this change for CURRENT >= 1400066.

The patch builds and installs fine on Poudriere and on my box. Working with the
patched wireguard-kmod seems to have no regressions so far.
