[arm][build_debian] Clean up qemu-arm-static bin after collecting post-versions info (#6289)

- Why I did it
scripts/collect_host_image_version_files.sh fails with below error:

scripts/collect_host_image_version_files.sh target ./fsroot
/usr/sbin/chroot: failed to run command 'post_run_buildinfo': No such file or directory
/bin/cp: cannot stat './fsroot/usr/local/share/buildinfo/post-versions': No such file or directory

- How I did it
Issues is because qemu-arm-static is removed before this step. So, I moved the cleanup step to the end.
