ima: added policy support for 'security.ima' type
The 'security.ima' extended attribute may contain either the file data's
hash or a digital signature. This patch adds support for requiring a
specific extended attribute type. It extends the IMA policy with a new
keyword 'appraise_type=imasig'. (Default is hash.)
Changelog v2:
- Fixed Documentation/ABI/testing/ima_policy option syntax
Changelog v1:
- Differentiate between 'required' vs. 'actual' extended attribute
