[PATCH 1/1] archvier.bbclass: fix copyleft filter behavior

[Kevin Strasser <kevin.strasser@linux.intel.com>]

copyleft_should_include() was only filtering out recipes that
contain a license in COPYLEFT_LICENSE_EXCLUDE. This change adds
the requirement that the recipe contain a copyleft license, as
defined by COPYLEFT_LICENSE_INCLUDE.

Also, filtering results were being mistakenly negated in tar_filter().
