license: Improve disk usage
Currently copies of the license files are made which wastes disk space and adversely affects performance. We can link these instead in most cases for small performance gains. (From OE-Core rev: 0b0f3631fd22f731b6aeedb73965e367b695028b) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
