fix: resolve rsync command bug in wush rsync

Fixed a bug that caused the `wush rsync` command to malfunction due to
residual references to an outdated variable. Removed unnecessary import
and adjusted the command construction to use the correct `overlayOpts`
structure. Added a temporary print statement for debugging.
