crypto/create_key: split directory creation

The code sets the umask before creating the key directory. We may run
into a problem where, if we need to create more leading
components in that path, they will also inherit the restrictive umask.
This is problematic when bootstrapping a new instance, as it might
create the base data directory with permissions that prevents some
processes, e.g., nginx, from accessin it.

Add anchors to docs

Also fix typos in raw image dependencies.
