Makefile: document default SHA-256 backend
Since 27dc04c5450 (sha256: add an SHA-256 implementation using libgcrypt, 2018-11-14) we've claimed to support a BLK_SHA256 flag, but there's no such SHA-256 backend. Instead we fall back on adding "sha256/block/sha256.o" to "LIB_OBJS" and adding "-DSHA256_BLK" to BASIC_CFLAGS.
