s390/cert_store: select CRYPTO_LIB_SHA256

Browse Source 
A build failure was reported when sha256() is not present:

gcc-13.1.0-nolibc/s390-linux/bin/s390-linux-ld: arch/s390/kernel/cert_store.o: in function `check_certificate_hash':
arch/s390/kernel/cert_store.c:267: undefined reference to `sha256'

Therefore make CONFIG_CERT_STORE select CRYPTO_LIB_SHA256.
