Subject: [PATCH] postinst: Make sure Flatcar extension folder exists

When a Flatcar extension file is created on an old node that doesn't yet
support them but the update will, and already downloads it, then we also
need to create the folder because it's not existing yet.

Fixes https://github.com/flatcar/Flatcar/issues/1788
