build-sys: Make dirs writable on rootfs creation

Autofoo make the dist dir as readonly. If we copy it, tools needing to
create sysfs entries will not be able to do so, because they can't
create the needed directories/files.

It would be much better if autofoo allowed to let the files as is
instead of converting them to read-only.
