Another pass at board status script

This reports relevant bits of information about a machine which is
running coreboot. This also includes a script to get revision info
from git, which we may want to split out into another patch.

A remote target can be specified since it is likely that the machine
used to develop the code is not the same machine being developed for.
The remote host must be set up for non-interactive root login.

Example: sh util/status/status.sh -r gizmoboard -u
