test(golden): pin current_exe scrub to CARGO_BIN_EXE for custom target dirs

The Windows verifier runs with CARGO_TARGET_DIR=target/windows-verify, so
the literal /target/{debug,release}/ scrub missed current_exe and the
artifact handoff golden diverged. Scrub the exact binary path reported by
CARGO_BIN_EXE_tokenzero to the default layout first; verified against a
custom CARGO_TARGET_DIR on Linux.
