This addresses a regression introduced in 407e3a4552,
which turned out to be "too strict", as there's old images that use, for example;
docker pull python:3.5.1-alpine
3.5.1-alpine: Pulling from library/python
unsupported media type application/octet-stream
Before 407e3a4552, such mediatypes were accepted;
docker pull python:3.5.1-alpine
3.5.1-alpine: Pulling from library/python

Status: Downloaded newer image for python:3.5.1-alpine

This patch copies the additional media-types, using the list of types that
were added in a215e15cb1, which fixed a
similar issue.
