Fix layer comparison and enable read-only checks

Browse Source 
fstest.CheckDirectoryEqual checks if any files in the diff matches a
list of known metadataFiles. This only happens if we specify the initial
layer as the first parameter and the mutated layer as the second.

This also enables the read-only view checks, as the bind filter allows
us to mount a layer as ro.
