libsframe needs to be copied when updating to runtime 23.08

Hi, this is a heads up.

`ar` since binutils >=2.40 links against libsframe but binutils is entirely in the SDK and not in platform runtime. So `libsframe` needs to be copied, else the `apply_extra` script won't work.

```
cp -a /usr/lib/$(gcc --print-multiarch)/libsframe.so* ${FLATPAK_DEST}/lib
```

Another option is to use bsdtar instead of ar.

Thanks
