[nrf fromlist] Bluetooth: Host: remove useless select in BT_HOST_CRYPTO_PRNG

PSA Crypto API always allow psa_generate_random() to be called (i.e. there
is no PSA_WANT_xxx symbol that can be used to disable it). How random
numbers are generated internally is a library internal detail, but the
end user (Bluetooth) does not need to worry about this.
