Update initialization script to create media directories (#479)

* Update initialization script to create media directories

- Added creation of new directories: `backups`, `profile`, `upload`, `thumbs`, and `encoded-video` within `${IMMICH_MEDIA_LOCATION}`.
- Ensured proper permissions are set for the new directories to maintain consistency.
The command

```bash

chown -R abc:abc \
    "${IMMICH_MEDIA_LOCATION}" \
    "${IMMICH_MEDIA_LOCATION}"/*
```
processes ${IMMICH_MEDIA_LOCATION}/library twice. If there are many files inside, it can significantly slow down the startup process.

* cleanup
