Bluetooth: update mgmt setup to use secure-connection for LE

The previous mgmt setup no longer working with the latest Raspberry Pi
OS, Linux 5.10.17 + BlueZ 5.50. Without a secure-connection feature
explicitly set, the LE connection initiated by the device may use a
different address type than the one used during bonding, causing the
connection to fail. This patch update uses the secure-connection and
turns off the unnecessary settings.

TEST=bluetooth_AdapterQuickHealth.AVL passed with Raspberry Pi with
TEST=kernel 5.10, 5.4, and 4.19.
