[Buildroot] Some files to be copied to root file systems such as openvpn keys, conf

[Jeremy Rosen <jeremy.rosen@openwide.fr>]

All file ownership are given to root in the fakeroot container,

the fakeroot container is applied after the overlay


So, (assuming I understant correctly what's going on) you don't neet to have these files owned by root in the overlay. Ownership will be changed while the final image is built
