Coverity's static analysis helpfully reported a memory leak introduced by 0f0e55d8 ("libbpf: Improve BTF sanitization handling"). While fixing it, I realized that btf__new() already creates a memory copy, so there is no need to do this. So this patch also fixes misleading btf__new() signature to make data into a `const void *` input parameter. And it avoids unnecessary memory allocation and copy in BTF sanitization code altogether.
