The original IMA buffer data measurement sizes were small (e.g. boot
command line), but the new buffer data measurement use cases have data
sizes that are a lot larger. Just as IMA measures the file data hash,
not the file data, IMA should similarly support the option for measuring
buffer data hash.
Introduce a boolean parameter to support measuring buffer data hash,
which would be much smaller, instead of the buffer itself.
