[PATCH] gitlab: fall back to commit hash in qemu-setup filename

[Stefan Hajnoczi]

Personal repos may not have release tags (v6.0.0, v6.1.0, etc) and this
causes cross_system_build_job to fail when pretty-printing a unique
qemu-setup-*.exe name:

  version="$(git describe --match v[0-9]*)";
             ^^^^^^^^^^ fails ^^^^^^^^^^^
  mv -v qemu-setup*.exe qemu-setup-${version}.exe;

Fall back to the short commit hash if necessary. This fixes CI failures
that Greg Kurz and I experienced in our personal repos.
