base/license.bbclass: expand wildcards in INCOMPATIBLE_LICENSE

The whitelist processing in code in base.bbclass does not play well with
wildcards in INCOMPATIBLE_LICENSES. The code expects bad_licenses to
contain actual license names, not wildcards.

Add incompatible_license_contains to replace bb.utils.contains(
"INCOMPATIBLE_LICENSE", **, **, **, d)
