[nrf toup] Add missing defined oberon_key_derivation.c

In line 568 of this file we use this function when either of
these two defines are set:
defined(PSA_NEED_OBERON_TLS12_PRF) ||
defined(PSA_NEED_OBERON_TLS12_PSK_TO_MS)

Add these two defines here as well to avoid a missing
function warning that we are getting.
