[PATCH 20/21] toaster: buildinfohelper Create a copy of the built layer and recipe

[Michael Wood <michael.g.wood@intel.com>]

Create a copy of the built layer and the recipes associated with it.
This is so that the user can view the historical information about a
build. i.e. a snapshot of the layer version and artifacts produced at
that build.
