RHAIENG-948: fix(ppc): build failure due to missing libjpeg-turbo-devel to build pillow

```
        The headers or library files could not be found for jpeg,
        a required dependency when compiling Pillow from source.

        Please see the install instructions at:

        https://pillow.readthedocs.io/en/latest/installation/basic-installation.html
```
