refactor: lua code cache: make load functions take a log directly.
This patch makes the functions ngx_http_lua_cache_loadbuffer() and ngx_http_lua_cache_loadfile() take an ngx_log_t* argument directly instead of an ngx_http_request_t* so that they can be used in contexts where an HTTP request is not available.
