some docker2aci generated images doesn't have an arch label. about docker2aci

[jonboulle]

One possible solution will be to set os=Linux if os is empty and arch=amd64 if arch is empty.

Seems reasonable, particularly if we could verify that Docker does the same or equivalent..?

This is problably due to an empty layerData.Architecture (probably before docker supported archs different than amd64).

Actually, that was a bug on docker2aci. We were ignoring the arch field 😳 #75

I tried some old docker images and I couldn't find any that didn't include os and arch

@iaguis great! Thanks!
