bus/call: Implement exception handling on call failures

The benefit of these exceptions over the current message error handling
is that we populate an sd_bus_error struct with the error data from the
sd_bus_call. In the cases where there is an underlying dbus error, we
will get more information from the sd_bus_error that is plumbed through
the exception message.

Tested:
  Built and booted a BMC + Host from a full tray poweroff with no
  failed units.
