bitbake: toaster: models Add update_package_list for CustomImageRecipe

Add a method to update the packages included list from the last
build, this effectively "synchronises" the package list from what
we think will happen at the Customise image stage with what
actually was produced with a build. It's not ideal to have this
function here but we also need to make sure that no race condition
of the user accessing this list and it being updated occurs.
