bug#33303: hex id for file system is incorrect or non-standard using uil 'id'

[L A Walsh]

Was looking to see when the underlying filesystem
changed in a path.

I used:
>  stat -f -c%f /
82100000000
stat -f -c%i /var
82200000000

There are way too many zeros, not to mention being left justfied
with zeros.

What I might expect to see is more like this:
821
or
822

mountpoint -d shows the maj:min for the given path (in decimal):
>  mountpoint -d /
8:33
>  mountpoint -d /tmp
8:34
