Update for OpenResty 1.27.1 compatibility

[GUI]

Currently if used with OpenResty 1.27.1, the following error is raised:

resty.openssl.auxiliary.nginx development mode doesn't support Nginx version 1027001, please compile nginx with lua-resty-openssl-aux-module or lua-kong-nginx-module.

• This tries to add compatibility with OpenResty 1.27.1 to the FFI development mode, similar to what was done in fix(aux/nginx) support openresty 1.25.3 in FFI path #147, but I'm not totally sure if this is the best way to go about this or if you want to be testing all these version variants.

• The new 1.27 tests pass in CI for me, however the older 1.19 and 1.21 tests are failing. But I think that's unrelated to these changes, since those older versions appear to be failing in CI already: https://github.com/fffonion/lua-resty-openssl/actions/runs/12705262705

• Update: Scratch this last question, I realized I wasn't testing this properly after adding lua-resty-openssl-aux-module. But everything works as expected with resty -e 'require "resty.openssl"; require "resty.openssl.auxiliary.nginx_c"' (just wasn't including the main module first).

  I realize this update is for the "development mode" and this FFI setup isn't recommended for production usage, but I was curious, is lua-resty-openssl-aux-module still functional? I compiled it with OpenResty 1.27.1, and while compiling it was successful, it doesn't appear to work, so lua-resty-openssl still seems to fallback to the FFI version. If I try to explicitly require the C version with lua-resty-openssl-aux-module installed, I still get this error:

  resty -e 'require "resty/openssl/auxiliary/nginx_c"'
  
  ERROR: ...or/lua/share/lua/5.1/resty/openssl/auxiliary/nginx_c.lua:98: declaration specifier expected near 'SSL'

  Am I doing something wrong with the lua-resty-openssl-aux-module installation (I didn't get any errors), or is it no longer compatible with newer versions of OpenResty and doing what's expected?

Thanks!

Hi @GUI thanks for the report, I'm just back from holiday so haven't been able to fix the build error you mentioned. But it's indeed unrelated. I have kicked the CI on this PR and once it's passed for 1.27.1 I can merged this.
