fix(ci): preserve VM runtime for E2E

The Rust cache restores target/ after VM runtime artifacts are staged,
overwriting target/vm-runtime-compressed before openshell-driver-vm is built.
Stage the compressed runtime outside target and pass that location through
OPENSHELL_VM_RUNTIME_COMPRESSED_DIR so build.rs can embed the supervisor.

Also locate the Helm split-ownership test repository root from the script
path rather than git rev-parse. The test runs in a container where the
GitHub checkout can be owned by a different UID and rejected as dubious
ownership.
