utils/add-custom-hashes: symlink linux-headers to linux

Most boards use BR2_KERNEL_HEADERS_AS_KERNEL with their custom kernels. So when creating their custom hash files, the linux-headers.hash is the same as linux.hash. In this case we symlink linux-headers to linux to make maintenance easier. Update the add-custom-hashes tool to explicitly handle this case.
