sectransp: add support for HTTP/2 in gcc builds

Before this patch `--http2` did not work in gcc builds with Secure
Transport, because ALPN relied on a compiler supporting the
`HAVE_BUILTIN_AVAILABLE` aka `__builtin_available()` feature. This
is clang-specific and missing from gcc (as of gcc v14).

Add support for ALPN and HTTP/2 when this compiler feature is missing.

Also drop test exceptions from GHA/macos in CI.
