Missing MIME types for ufs and uzip files (images)

```
FreeBSD% file --mime-type '/home/user/Desktop/system.ufs'
/home/user/Desktop/system.ufs: application/octet-stream

FreeBSD% file --mime-type '/home/user/Desktop/system.uzip'
/home/user/Desktop/system.uzip: text/x-shellscript

FreeBSD% grep -r "ufs" /usr/local/share/mime
(nothing)

FreeBSD% grep -r "ufs" /usr/local/share/mime
(nothing)
```

Can we get these defined?

Workaround: Add `.img` to the extension of the files in question so they that get recognized at least as `application/x-raw-disk-image`.
