libknet1: musl fix
Upstream provided musl fix, I took diff and applied to latest release, see https://github.com/kronosnet/kronosnet/commit/512e433b0b3d8bf14818dcb8c8eb7748d7e899be

I also "enabled" building of libnozzle libraries from kronosnet, so it does not diverge from other distros.

A patch file from https://github.com/void-linux/void-packages/pull/14215.patch is attached
