Rules will only be installed if a device specific config.xml overrides
the default values of mark and mask.
This change also fixes a bug where wakeup rules added by the wakeup
controller would never be removed because updateInterfaces() is not
invoked on wifi network change or disable.
Test: as follows
- built
- flashed
- booted
- Manually verified that mask/mark is set correctly
