[PATCH BlueZ v1] mgmt-tester: Add LL Privacy host-resolved RPA scan checks

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

Controllers with LL Privacy resolve RPAs themselves, so peers with an
IRK can be kept in the accept list and passive scanning shall use the
accept list filter policy.
