Add the bpf_lookup_user_key(), bpf_lookup_system_key() and bpf_key_put() kfuncs, to respectively search a key with a given key handle serial number and flags, obtain a key from a pre-determined ID defined in include/linux/verification.h, and cleanup. Introduce system_keyring_id_check() to validate the keyring ID parameter of bpf_lookup_system_key().
