Add init_priority to generated code

Fix a issue(crash) on `FEATURE_SENSORS_CACHE` is enabled.
As below backtrace:
```
...
4  0x75ff9a34 in initSensorMatches () at ../../../../../../workspace/sources/phosphor-ipmi-host/sensorhandler.cpp:153
5  0x75f887a8 in register_netfn_sen_functions () at ../../../../../../workspace/sources/phosphor-ipmi-host/sensorhandler.cpp:1561
...
```

This issue is caused by `ipmi::sensor::sensors` is not initialized when
register_netfn_sen_functions is called.
Add init_priority to generated code to fix this issue.

Tested: Build okay and no crash.
