crypto: sa2ul - add Kconfig selects to fix build error

sa2ul.c uses sha{1,256,512}_zero_message_hash, so select the
Kconfig symbols that provide those, like other crypto drivers do.

Fixes this build error:

ld: drivers/crypto/sa2ul.o: in function `sa_sha_digest':
sa2ul.c:(.text+0x2b25): undefined reference to `sha512_zero_message_hash'

Fixes: 7694b6c ("crypto: sa2ul - Add crypto driver")
