INCOMPATIBLE_LICENSE: support for spdx and pkg licenses

This adds a few things to the incompatible license functionality

1. INCOMPATIBLE_LICENSE was unable to distinguish any variation
within LICENSE (e.g. GPLv3 v. GPLv3.0). This now utilizes the
SPDXLICENSEMAP of the license indicated as INCOMPATIBLE_LICENSE

2. Given a recipe where the main LICENSE was incompatible but
a package of the recipe was compatible, the entire recipe would
be excluded. This allows us some finer grained control over what
exactly gets excluded.
