RFC PATCH 1/1 mktree: handle CKPT_HDR_LSM_INFO header type

[ This patch is against the userspace c/r code at
git://git.ncl.cs.columbia.edu/pub/git/user-cr.git ]

This is a variable length buffer type intended to contain LSM-specific version information, for instance a policy version number of sha1sum of the policy.
