PHP 8.1.34 has a known issue where the stream cookie functions' signatures don't match the fopencookie API expectations on certain platforms. The compiler is treating this as an error (-Werror). Updating the Dockerfile to add a compiler flag that treats this specific incompatibility as a warning rather than an error.
The -Wno-error=incompatible-pointer-types flag is only needed for PHP 8.1 due to a known fopencookie signature mismatch. Newer PHP versions build without it, so scope the suppression to 8.1 only.
