[PATCH v3 2/4] package_manager.py: fixes for multilib deb packaging builds

[Matt Madison <matt@madison.systems>]

* tmp/deploy/deb subdirectories do not get hyphens replaced
  with underscores, so don't do that translation when building
  the sources list.

* Fix MULTILIB_VARIANTS handling to be more general and
  work for all architectures

* Also include a fix for a warning generated by apt
  due to missing apt/preferences.d directory.
