dh-dkms missing in build dependencies

[melianmiko]

Without dh-dkms, when trying to build on Debian, I got an error:

dpkg-buildpackage: info: source package amneziawg-linux-kmod  
dpkg-buildpackage: info: source version 1.0.0  
dpkg-buildpackage: info: source distribution unstable  
dpkg-buildpackage: info: source changed by unidentified attacker <[email protected]>  
dpkg-buildpackage: info: host architecture amd64  
dpkg-source --before-build .  
debian/rules clean  
dh clean --with dkms  
dh: warning: Compatibility levels before 10 are deprecated (level 9 in use)

Installing dh-dkms solves the problem.
