[PATCH 3/4] security: Make security_hook_heads use definitions in lsm_hook_types.h

[Sargun Dhillon <sargun@sargun.me>]

This change makes it so rather than having to duplicate the list
of heads in struct security_hook_heads, the structure is generated
based upon the structured hooks in lsm_hook_types.h.
