Nacho Barrientos 906dbb280d systemd: byte order to host before using the lifetime 
I've seen this in `NetworkManager-1.34.0-0.3.el8.x86_64` (latest in CentOS
Stream 8 at the time of writing this message) which does not use the latest
Systemd but probably the code base is the same (see
51f93e00a2).

Before the patch:

```
libsystemd: eth0: DHCPv6 client: T1 expires in 34y 3w 6d 45min 31s
libsystemd: eth0: DHCPv6 client: T2 expires in 54y 5month 3w 3d 23h 20min 35s
```

After the patch:

```
libsystemd: eth0: DHCPv6 client: T1 expires in 3d 7h 58min 3s
libsystemd: eth0: DHCPv6 client: T2 expires in 5d 2h 26min 50s
```

same box (x86_64 system) and same DHCPv6 server.

This regression has likely been introduced by 8a8955507af363c31297bbc5df79852db4ad39d6.

libnm-systemd-core

This is a fork of systemd source files that are compiled as a static library with network helpers.

We use systemd's DHCPv6 and LLDP library, by forking their code.

We also still use their DHCPv4 library, but that is about to be replaced by nettools' n-dhcp4.

This approach of code-reuse is very cumbersome, and we should replace systemd code by a proper library (like nettools).

We should not use systemd directly from our sources, beyond what we really need.
