[OpenWrt-Devel] [PATCH v2] image.mk: Create a manifest file of installed packages as a build artifact

[Pushpal Sidhu]

A few linux BSP's create a manifest file of installed packages for a given
target in order to help them understand exactly what's on their images. Create
one for OpenWrt as well as a build artifact since many users have an affinity to
prune down on packages to save valuable flash space.
