start: Fix print_top_failing_dir for /var/lib/lxc

In the case where /var/lib/lxc itself was not accessible, print_top_failing_dir would fail to print the error message. This fixes it and also change the initial access check for X_OK instead of R_OK (to match what we actually need and print_top_failing_dir's own check).
