project-lakitu: Use hostname from net-tools

ChromeOS switched to using hostname from coreutils for space efficiency
reasons. However, hostname from net-tools has more features, and our
users may depend on them (our tests depend on them). Since we're not
currently struggling for rootfs space, let's keep hostname from
net-tools.
