[PATCH v2 1/6] ima: rename IMA_ACTION_FLAGS to IMA_NONACTION_FLAGS

[Mimi Zohar]

Simple policy rule options, such as fowner, uid, or euid, can be checked
immediately, while other policy rule options, such as requiring a file
signature, need to be deferred.

The 'flags' field in the integrity_iint_cache struct contains the policy
action', 'subaction', and non action/subaction.

action: measure/measured, appraise/appraised, (collect)/collected,
        audit/audited
subaction: appraise status for each hook (e.g. file, mmap, bprm, read,
        creds)
non action/subaction: deferred policy rule options and state

Rename the IMA_ACTION_FLAGS to IMA_NONACTION_FLAGS.
