remove inheritance from apt_package

the dpkg_package provider is not strictly an apt_package provider so
code-sharing via inheritance was broken.

this copypastas some code from apt_package back into dpkg_provider and
does some rearrangement.

future code sharing between these two should be done via mixin or
via composition (e.g. mixin for #run_noninteractive)
