archiver.bbclass: make it can filter the license

* Filter the license (default: no), the recipe whose license in
  COPYLEFT_LICENSE_INCLUDE will be included, and in
  COPYLEFT_LICENSE_EXCLUDE will be excluded.

* The user can set the recipe type that would be archived (native,
  target, and so on), deafult to all.

The copyleft_filter.bbclass is come from copyleft_compliance.bbclass,
which is used by both copyleft_compliance.bbclass and archiver.bbclass.
