Add a compatibility EVP_CIPH_OCB_MODE value.

Node references it these days. Also replace the no-op modes with negative
numbers rather than zero. Stream ciphers like RC4 report a "mode" of zero, so
code comparing the mode to a dummy value will get confused.

(I came across https://github.com/nodejs/node/pull/23635, though we'd have run
into it sooner or later anyway. Better to just define the value and avoid ifdef
proliferation.)
