core: Use ADD_FILES checkout mode for "setup"

Browse Source 
Prep for unified core 🌐.  On the treecompose path we inject
`/usr/etc/passwd`, and trying to overlay the setup package on top
with the default `UNION_IDENTICAL` fails.

This is obviously a hack; but I can't think of a way to do this significantly
better. (We could do a DB query for the owner of `/etc/passwd`, but eh.)

Closes: #1098
