[OpenAFS-port-darwin] update to afstokens app

[David Botsch]

Hi, all.

A slight update to the afstokens app (all platforms, sources, and all 
binaries):

getting tokens in multiple realms now works properly (though, until the 
afs source is patched, you may see a console error message about no 
config directory being present... the afs source patch will cause the 
error message to be unseen).
