Samples: Bluetooth: Fix peripheral with multiple identities sample

Fix issue in the peripheral with multiple identities sample.
In the Kconfig.sysbuild file, both NRF_DEFAULT_BLUETOOTH
(which enables hci_ipc) and NRF_DEFAULT_IPC_RADIO
(which enables ipc_radio) are enabled.
Only NRF_DEFAULT_IPC_RADIO is required.
