license.bbclass: Symbolic links of generic license

This is to reduce the size of licenses added to images. With this
commit license.manifest, original license and generic license
adds about .5M to a core-image-minimal image, substantially less
than what is currently occuring when COPY_LIC_MANIFEST and
COPY_LIC_DIRS are set.
