[PATCH v2 3/8] module: Give 'enum pkey_id_type' a more specific name

["Thomas Weißschuh" <thomas.weissschuh@linutronix.de>]

This enum originates in generic cryptographic code and has a very
generic name. Nowadays it is only used for module signatures.

As this enum is going to be exposed in a UAPI header, give it a more
specific name for clarity and consistency.
