n-dhcp4 fails to build with clang and ASan

[evverx]

It was addressed in n-dhcp4 itself in #38 but it seems the c-siphash submodule hasn't been bumped yet. Is there any chance it can be bumped to something containing c-util/c-siphash@203347c?

(I can bump it before building it but it would be better if it was possible to drop that kludge)

I really need to sync all the c-utils and nettools, as well as the CI. I have it on my radar!

[evverx]

I opened nettools/n-acd#14. I think it should make them all buildable with clang and ASan as soon as the deps are bumped.
