When using --root option in criu dump, when the mountpoint passed
contains a symbolic link, criu does not resolve its parent correctly.
e.g when passing --root /run/rootfs, dump finishes successfully;
but when /var/run/rootfs is passed, where /var/run is symbolic link to
/run it exits with error "New root and old root are the same".
