Remove build flag for Jolla phone defaults.

This should be handled by the front-end.  They're just default values, and by design are easy to override by editing the config file.

Also, the code guards are malformed, since jp1 is not a variable.  This was evaluating to true even when CFG_DEFAULTS wasn't defined in our makefile.
```#if CFG_DEFAULTS == jp1```
