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meta-security-framework but it is no longer maintained therefore it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.

To avoid having linux-%.bbappend included in targets unrelated to the
linux kernel, rename linux-%.bbappend to linux-yocto%.bbappend.

Append ':append' to do_configure so it does not replace all existing
do_configure's.
Only run 'sed' when DISTRO_FEATURES contains 'ima' and the .config file
exists.

Drop the kernel config option CONFIG_SQUASHFS_XATTR=y from ima.cfg.
Instead, require projects that use squashfs to set this option.
