Merge: fix /app/site_media permission

See merge request !32

/app/site_media is mapped to a named volume when deploying with docker compose as part of AURA Playout. Docker creates the directory as root where a named volume should be mapped to if it does not already exist. We therefore create the mount point in advance and set permissions in order to give the aura(app) user access. #184
