bus: add error handling for bus-open calls

sd-bus can return ENOMEDIUM in some cases for bus-open calls, so
we need to detect this condition rather than blindly ignoring the
return value.  Add appropriate error handling.

Tested:
```
$ sudo builddir/example/calculator-server
Password:
terminate called after throwing an instance of 'sdbusplus::exception::SdBusError'
  what():  sdbusplus::bus::bus sdbusplus::bus::new_default(): System.Error.ENOMEDIUM: No medium found
zsh: IOT instruction  sudo builddir/example/calculator-server
```
