[PATCH ghau85 v1] ima: add support for AUDIT_INTEGRITY_EVM_XATTR records

[Richard Guy Briggs <rgb@redhat.com>]

In commit fa516b6 ("EVM: Allow runtime modification of the set of verified
xattrs") support was added in the kernel for the
AUDIT_INTEGRITY_EVM_XATTR record with the EVM_ADD_XATTRS config option.
Its record number is 1806. It has a field "xattr=" with result field
"res=".

Add support for the record type number.  Since the xattr field isn't
searchable, a parser wasn't necessary.
