OpenSSL: Remove md4_vector() from CONFIG_FIPS=y builds

MD4 is not allowed in such builds, so comment out md4_vector() from the
build to force compile time failures for cases that cannot be supported
instead of failing the MD¤ operations at runtime. This makes it easier
to detect and fix accidental cases where MD4 could still be used in some
older protocols.
