devtool: build-image: allow specifying packages to add to image

Provide an option to devtool build-image to specify the list of packages
instead of taking the list of packages produced by recipes in the
workspace. Sometimes you don't want all of these packages; other times
you want to add more.

This is the most immediate fix for [YOCTO #8855], though it is a little
crude so I would like to provide better means of customising the image
contents later.
