The /etc/systemd/network/ folder didn't exist by default, which caused
static IP assignment via the kernel command line being broken
(The format ip=<ip>::<gateway>:<netmask>:<hostname>:<iface>:none[:<dns1>[:<dns2>]]
is documented in https://docs.flatcar-linux.org/ignition/network-configuration/#using-static-ip-addresses-with-ignition
and parsed in the initramfs).
Create the folder before trying to write a networkd unit into it.

Reported in flatcar/Flatcar#148

How to use

Boot a QEMU VM and add this kernel parameter in GRUB:

ip=10.0.2.15::10.0.2.2:255.255.255.0::eth0:none:1.1.1.1:8.8.8.8

Currently journalctl --e -u dracut-cmdline show these errors which should be gone with the patch:

dracut-cmdline[191]: //lib/dracut/hooks/cmdline/99-parse-ip-for-networkd.sh: line 76: /etc/systemd/network/10-dracut-cmdline-99.network: No such file or directory

Testing done

The error messages are gone following the instructions above. I didn't test it with something else.
