No longer mount platform partitions

- Kernel writes Journal log when system-data is mounted
- Modifying data with flashing can break partition
- Although fsck recovers partition, we have to prevent
  this situation

- In addition, USB mountpoint is changed
  - mkdir in /opt is failed because of SMACK
  - So, move to /tmp which has '*' SMACK label
