[build]: allow single src file to build multiple independent debian p… (#349)

add_derived_package setup dependency between the main deb and derived deb.
The derived deb depends on the main deb and need to install the main deb.

add_extra_package does not setup dependency between the main deb and peer deb,
does not require to install the main deb.

* rename add_peer_packages to add_extra_packages
