[zep noup] config_psa: include legacy module adjusting in MCUBOOT

MCUboot has its own version of the PSA Crypto core, named
"thin_psa_crypto_core.c" which is included in MCUboot's
build process when the MCUBOOT_USE_PSA_CRYPTO build symbol is
set. MCUBOOT_USE_PSA_CRYPTO mimics what MBEDTLS_PSA_CRYPTO_C
does for the official Mbed TLS, so we need to replicate
this symbol in "config_psa.h" in order to get the proper
PSA builtin support.
