[PATCH 1/1] image: create an image manifest listing installed packages

[<Cedric_Hombourger@mentor.com>]

From: Cedric Hombourger <Cedric_Hombourger@mentor.com>

Produce an image manifest that lists all packages installed into the
image. Note the architecture, version and (when specified) the source
package. The package details are tab-separated and may easily be
imported into a spreadsheet (e.g. should you need to provide a Bill
Of Material).
