fix: remove net-tools from BuildRequires to fix Fedora 43 build

On Fedora 43, net-tools pulls in systemd which conflicts with
systemd-standalone-tmpfiles in container build environments.
Pre-define ZM_PATH_ARP, ZM_PATH_ARP_SCAN, ZM_PATH_IP, and
ZM_PATH_IFCONFIG in the cmake call instead of relying on
find_program() at build time.
