Implement io.ReaderAt on docker fetch reader#11981

Conversation
I was working on treating a remote as a content provider and ran into the stream backing the fetch only implementing io.Seeker. I shimmed an io.ReaderAt implementation by calling seek under the hood, but this is of course not a faithful io.ReaderAt implementation. This just implements a correct io.ReaderAt implementation directly. Signed-off-by: Brian Goff <cpuguy83@gmail.com>
