ONC: Use HexSSID instead of SSID.

- Comparison of a network policy with network will use HexSSID now.
- Translation from ONC to Shill now copies the HexSSID instead of translating SSID.
- Fix ONC validation of HexSSID/SSID to be case insensitive.
- When setting an ONC: SSID will be ignored if HexSSID is present
- Reading network properties reports a HexSSID in ONC.
