Comment 1 for bug 1704979

My first proposition for quickly dealing with this is: skipping the test for arches other than amd64 and i386. They're not the target for the ubuntu-image tool (I can't imagine a real use-case) - especially that we're only supporting ubuntu-image for amd64 and i386 in the store.

If needed, we can dive in and try to find out why there are issues with the core snap on those arches. Anyway, it doesn't seem to be related to u-i itself.
