Subject: [PATCH] tools: fix build without LIBCRYPTO support

Commit cb9faa6f98ae ("tools: Use a single target-independent config to
enable OpenSSL") introduced a target-independent configuration to build
crypto features in host tools.

But since commit 2c21256b27d7 ("hash: Use Kconfig to enable hashing in
host tools and SPL") the build without OpenSSL is broken, due to FIT
signature/encryption features. Add missing conditional compilation
tokens to fix this.
