init: fix sysfs mount arguments
It is not good idea to pass empty 'source' argument to mount(2) because
libmount complains about incorrect /proc/self/mountinfo structure. This
affects many applications such as findmnt, umount and etc.
Let's add fake source argument to sysfs mount command as we do with all other
filesystems.
