audit dockerfile: replace deprecated MAINTAINER lookup

Browse source 
The MAINTAINER instruction was deprecated in 2017 in favor of an OCI
label "org.opencontainers.image.authors".

This patch replaces the MAINTAINER line lookup for this label in
Dockerfiles.

see: https://docs.docker.com/reference/build-checks/maintainer-deprecated/
