fix DockerSchema1RegistrySuite.TestPullFailsWithAlteredLayer 

This test was failing if after the busybox image switched to a
single layer.

The test fails because it alters the data of an empty layer and
relies on a side effect of another empty layer not being skipped
on pull to pass.

(The original patch was provided by Tonis Tiigi)
