Subject: python/pkgsrcrecords.cc: Unify dep handling -- part 2:
 SourceRecords.build_depends

Change apt_pkg.SourceRecords.build_depends to match exactly the interface of
Version.depends_list_str just with different keys (e.g. Build-Depends).

+ Closes: #468123 - there is no need anymore for binding CompType or
  CompTypeDeb, because we don't return integer values for CompType
  anymore.

   * Unification of dependency handling:
     - apt_pkg.parse_[src_]depends() now use CompType instead of CompTypeDeb
       (i.e. < instead of <<) to match the interface of Version.depends_list_str
