Add support for bmcrebootoff and bmcrebooton

In the view of having the system available in fail state, it would be a
necessity to have BMC stay in error state and not take reset due to any
recovery policy that is specified in the service files. This patch puts the
override for reboot, poweroff and halt requests to make those, a NO-OP

If the user needs to reboot the BMC, then "bmcrebooton" must be executed prior
to doing the reset.

Tested:

root@witherspoon:/tmp# cd /run/systemd/system/
root@witherspoon:/run/systemd/system# ls

root@witherspoon:/run/systemd/system# /tmp/obmcutil bmcrebootoff
