KEYS: Reserve an extra certificate symbol for inserting without recompiling
Place a system_extra_cert buffer of configurable size, right after the system_certificate_list, so that inserted keys can be readily processed by the existing mechanism. Added script takes a key file and a kernel image and inserts its contents to the reserved area. The system_certificate_list_size is also adjusted accordingly. Call the script as: scripts/insert-sys-cert -b <vmlinux> -c <certfile> If vmlinux has no symbol table, supply System.map file with -s flag. Subsequent runs replace the previously inserted key, instead of appending the new one.
