UBUNTU: [debian] support for ship_extras_package=false

If optional .mk variable 'ship_extras_package' is explicitly set to false,
then do not construct the linux-image-extra package; instead just log all
of the "extra" modules which were pointlessly built yet won't be shipped.
This feature may be useful for config debugging and for custom kernel
development.
