added docker file permission instructions again

I screwed up my initial commit, so here goes again. That's what i get for using the github gui...

I added the instructions to make the ipfs_data and ipfs_staging globally readable, which prevents permission errors.

It may be better to limit permissions in some way, to prevent potential security risks.
