KEYS: Add a key restriction struct

Key link restrictions require restriction-specific data as well as a
restriction-specific function pointer. As a first step toward replacing
the restrict_link pointer in struct key, define a more general
key_restriction structure that captures the required function, key, and
key type pointers. Key type modules should not be pinned on account of
this key type pointer because the pointer will be cleared by the garbage
collector if the key type is unregistered.
