From: Kristof Provost <k...@freebsd.org>
The libnv check doesn't work as expected on FreeBSD 14.x, because
FreeBSD has namespaced libnv to avoid conflicts with libnvpair.
This means that the naive check generated by AC_CHECK_LIB() fails to
detect libnv even though it's present.
Instead check for the if_ovpn.h header. This is a more accurate check
anyway, as libnv is present on FreeBSD versions prior to 14 (which do
not support DCO).
