Qemu: Resolve undefined reference issue in CVE-2023-2861

The commit [https://github.com/openembedded/openembedded-core/commit/9bd4ddeb4b5efc65b0514d50d6991211271924c1] backports fix for CVE-2023-2861 for version 6.2.0.
The 'qemu_fstat' in `do_create_others' is not defined which leads to the undefined symbol error on certain architectures.

Also, the commit message says "(Mjt: drop adding qemu_fstat wrapper for 7.2 where wrappers aren't used)". So either the wrapper has to be dropped or it has to be defined.

Hence, backported the main patch rather than the cherry picked one.
