Alexander Shishkin 7765095441 mount: pass NULL, not "", as "data" to mount syscall if we have no opts ...

When mounting a filesystem without any additional options (data parameter
to the mount(2) syscall), pass NULL instead of an empty string like GNU
mount does. This fixes, for example mounting cgroup fs with bbox mount.
