Bluetooth: samples: scan_adv: Select BROADCASTER and OBSERVER

Explicitly select CONFIG_BLUETOOTH_BROADCASTER and
CONFIG_BLUETOOTH_OBSERVER in the scan_adv sample.

If the Controller is included without connections support
then only broadcaster support is compiled in by default,
hence add broadcaster and observer role support explicitly
in the prj.conf file.
