[oe] [PATCH 2/2] src_distribute.bbclass: distribute only SRC_DISTRIBUTE_LICENSES

[Otavio Salvador]

A distro can require conf/licenses.conf or set SRC_DISTRIBUTE_LICENSES
selecting which licenses are wanted to be distributed. In case it is
empty or undefined we default to distribute all licenses to not break
backward compatibility.
