Limit multiple platform manifests to one for size check

ibuildthecloud · ibuildthecloud · commit 1161409779f0 · 2019-08-08T14:16:27.000-07:00
client.Pull will only pull one matching platform by default.
When checking the size of image we match that behavior so that
we don't look for multiple platforms that might not exist on disk.
