fix support for glibc >= 2.41

[sadguitarius]

I'm unable to build Petalinux because the sched_attr struct in linux-user/syscall.c conflicts with the one provided by glibc 2.41, which is the current version on Arch Linux (I know Arch is not officially supported but the rest of the build is working fine up to this point). I did try manually editing the repo with petalinux-devtool modify but that doesn't work on qemu-xilinx-native due to some submodule problems. As far as I can tell, updating here would be the easiest way to fix it.

See here for further explanation and the fix, which has already been added to the QEMU main branch. Thank you!

Ugh ok I tried submitting a PR and then realized not only was mine automatically closed but that someone else had already tried to do the same thing. The automated message redirects to the QEMU gitlab where this has already been fixed. Is there no way to submit a PR for the Xilinx fork??
