Add the missing binary into Palmetto config file

Palmetto.py did not have discover_system_state.py and this patch is
to update that. discover_system_state.py is responsible for looking
at power restoration policy set by the user and then taking appropriate
actions when BMC comes back from any reboot / power cycle and reaches
BMC_READY state.  Actions could be :
1) Leave the system in power off state.
2) Power on the box.
3) Restore the last state which can be either #1 or #2 above.
