main.conf: Fix Privacy modes

Device privacy 0x01 uses RPA regardless of the discoverable setting thus
it conforms to network mode not device mode.

Also this improves documentation to state what is the expectation of
each mode since it may not have been very clear by just using the terms
from the spec.

 # Default privacy setting.

+# Possible values: "off", "network/on", "device/limited"
+# "network/on": a device will only accept advertising packets from peer devices

+# devices since it requires the use of RPA(s) all the time.
+# "device/limited": A device in device privacy mode is only concerned about the

+# address, even if the peer device has distributed its IRK in the past.
