fix(dhcp): can not renew an ip address

The dhcp server is systemd-networkd, and the dhcp
plugin can request an ip but can not renew it.
The systemd-networkd just ignore the renew request.

Follow the https://datatracker.ietf.org/doc/html/rfc2131#section-4.3.6,
following options must not be sent in renew

- Requested IP Address
- Server Identifier

Since the upstream code has been inactive for 6 years,
we should switch to another dhcpv4 library.
The new selected one is https://github.com/insomniacslk/dhcp.

+# v1.1.1
+
+- [Bug Fix]: fix test compilation on big endian machines.
+
+# v1.1.0
+
+**This is the first release of package packet that only supports Go 1.18+. Users
+on older versions of Go must use v1.0.0.**
+
+- [Improvement]: drop support for older versions of Go so we can begin using
+  modern versions of `x/sys` and other dependencies.
+
+## v1.0.0
+
+**This is the last release of package vsock that supports Go 1.17 and below.**
+
+- Initial stable commit! The API is mostly a direct translation of the previous
+  `github.com/mdlayher/raw` package APIs, with some updates to make everything
+  focused explicitly on Linux and `AF_PACKET` sockets. Functionally, the two
+  packages are equivalent, and `*raw.Conn` is now backed by `*packet.Conn` in
+  the latest version of the `raw` package.
