license: simple verification of LICENSE_<pkg> values

Browse Source 
LICENSE should be a superset of all LICENSE_<pkg> values. That is,
LICENSE should contain all licenses and LICENSE_<pkg> can be used to
"filter" this on a per-package basis. LICENSE_<pkg> shouldn't contain
anything that isn't specified in LICENSE.

This patch implements simple checking of LICENSE_<pkg> values. It does
do not do advanced parsing/matching of license expressions, but,
checks that all licenses mentioned in LICENSE_<pkg> are also specified in
LICENSE. A warning is printed if problems are found.
