samples: Bluetooth: df: Fix problem with samples split build

Fix problem with building sample applications where Host is
split from Controller into separate binaries. In that situation
samples does not have access to controllers Kconfig options.
To optimize memory usage by an application, disable not needed
features (angle of arrival or angle of departure).
