[LTP] [PATCH v2 27/33] lapi/keyctl.h: Add capability fallback defines

[Andrea Cervesato <andrea.cervesato@suse.de>]

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

Add fallback definitions for KEYCTL_CAPABILITIES, KEYCTL_CAPS0_*,
and KEYCTL_CAPS1_* constants, and update safe_keyctl to handle
KEYCTL_CAPABILITIES.
