Create initial skeleton of host check code

This sequence of commits will be the application
that runs after a BMC reset when it's detected that
pgood is on.  This applications job is to check
whether the host is running, and if it is, to
create a specific file in the filesystem that
will prevent the host power on targets services
from executing.
