meta-quanta: meta-gsj: Cleanup for Yocto override syntax change

Cleanup with
```
convert-overrides.py meta-quanta/meta-gsj

git grep "_[a-z0-9_/-]*[ :]" -- meta-quanta/meta-gsj

git grep -l _gsj -- meta-quanta/meta-gsj \
  | xargs sed -i 's/_gsj/:gsj/'
```

Note:
Need to revert the change to BBFILE_PATTERN and LAYERSERIES_COMPAT.

After cleanup
```
$ git grep "_[a-z0-9_/-]*[ :]" -- meta-quanta/meta-gsj/ | grep '.bb'
