test: make ssl/xrpc tests work with OpenResty 1.29.2.4 runtime

The apisix-runtime build moved to OpenResty 1.29.2.4 (lua-resty-core /
stream-lua 0.0.19), which changed behavior these tests assert on:

- t/ssl.t TEST 3/5: the lua-resty-core tlshandshake patch reworded its
  validation errors ("... both setting" -> "... cannot both be set";
  "bad client_cert option type" -> "bad client_cert_path option type").
  Match both wordings with a version-tolerant regex so the test passes on
  both runtimes.

- t/stream/xrpc/{downstream,upstream}.t: assert stream-lua internal
  buffer-allocation debug logs that no longer appear in stream-lua 0.0.19.
  Exclude them on apisix-runtime; they still run on api7ee-runtime
  (OR 1.21, stream-lua 0.0.16) for functional coverage.
