lib/oe/package_manager.py: fixes for dpkg backend

This commit contains the following fixes:
 * pass the apt config directory to the DpkgPM constructor, so one can
   instantiate this class multiple times and give it different config
   files (like for creating SDK);
 * change constructor argument name from 'dpkg_archs' to 'base_archs';
 * export APT_CONFIG environment variable before calling apt-get, not in
   constructor. If done in constructor, the last class instantiation,
   sets the environment, which is note desireable;
