vtpmmgr: add example control tools

The manage-vtpmmgr.pl script is an example client for interacting with
the TPM Manager; it is intended to run in a management domain with a
vTPM (which may be dom0).  It is used to create and manage vTPMs and
vTPM groups.

The calc.pl script is an example manager of a vTPM group.  It signs
the configuration lists used by the TPM Manager with a locally held
private key.
