[LTP] [PATCH 21/33] lapi/keyctl.h: Add fallback definitions for public key ops

[Andrea Cervesato]

From: Andrea Cervesato <andrea.cervesato@suse.com>

Add fallback definitions for KEYCTL_PKEY_QUERY, KEYCTL_PKEY_ENCRYPT,
KEYCTL_PKEY_DECRYPT, KEYCTL_PKEY_SIGN, KEYCTL_PKEY_VERIFY, and
KEYCTL_SUPPORTS_*, as well as fallback structs keyctl_pkey_query
and keyctl_pkey_params when built without keyutils.h or linux/keyctl.h.
