Subject: [PATCH] ci(openkylin): pin HOME so rustup installs in the container
 job

The openKylin image runs as root while Actions sets HOME=/github/home;
dtolnay/rust-toolchain fails with "$HOME differs from euid-obtained home
directory" and the job never reaches the build. Pin HOME/CARGO_HOME/
RUSTUP_HOME to root's for the whole job.
