md4: fix compilation with OpenSSL 1.x with md4 disabled

If OpenSSL 1.x is used, and it is configured with md4 disabled,
OPENSSL_NO_MD4 is defined in opensslconf.h, but this header was not
included before checking for this define.

Later in md4.c, openssl/md4.h is included, and it includes that header
indirectly, leading to inconsistency within md4.c.

Since the md4.h branch was taken, wincrypt.h (or others) is not
included, and later below the USE_WIN32_CRYPTO branch is taken, but the
types are not defined.

Closes #14218
