Add Marta and myself as maintainers for meta-security and the other
embedded layers that Armin had been maintaining. To avoid Armin
getting bugged about individual recipes, set the RECIPE_MAINTAINER
variables to myself for now as a starting point that can be adjusted
as things get more settled.

When IMA and EVM are used for file appraisal then EVM verifies the
signature stored in security.evm. This signature covers file metadata
(uid, gid, mode bits, etc.) as well as the security.ima xattr.
Therefore, it is sufficient that only files' hashes are stored in
security.ima. This also leads to slight performance improvements
since IMA appraisal will then only verify that a file's hash matches
the expected hash stored in security.ima. EVM will ensure that the
signature over all the file metadata and security.ima xattr is
correct. Therefore, give the user control over whether to store file
signatures (--imasig) in ima.security or hashes (--imahash) by
setting the option in IMA_EVM_IMA_XATTR_OPT.
Only test-verify an IMA signature if --imasig is used as the option.

Introduce IMA_EVM_PRIVKEY_KEY_OPT to pass additional options to evmctl
when signing files. An example is --keyid <id> that makes evmctl use
a specific key id when signing files.

Add audit.cfg configuration fragment. By default it is not appended
to SRC_URI. It allows enabling the audit kernel subsystem which may
help to debug appraisal issues. Boot with "integrity_audit=1" to
capture a more complete set of events in /var/log/audit/.
Previously the same configuration fragment was provided by layer
meta-security-framework but it is no longer maintained therefore it
makes sense to have audit.cfg in layer meta-integrity.

The IMA policy will be specified using the IMA_EVM_POLICY variable since
systemd will not be involved in loading the policy but the init script will
load it.

data/debug-keys will be reused for demo modsign keys, so rename
IMA_EVM_BASE to more generic INTEGRITY_BASE.
