fix issue in test with symlinks.

libruby.so.4.0 is a symlink whose target (libruby.so.4.0.0 or similar) doesn't exist in the extracted temp dir — it's a dangling symlink. stat() follows symlinks and fails with ENOENT on dangling ones. lstat() operates on the symlink itself and succeeds, then unlink() removes the symlink cleanly.
