[qtbase] Skip rootfs in QStorageInfo. Contributes to JB#50211

Skips rootfs device since there is another device for /. It may exist
because / has been pivot from rootfs to ext4 on boot but it's typically
not useful. This allows another device mounted to the same mount point
to overwrite rootfs device.
