System users are shipped in /usr/etc/passwd instead of /lib/passwd

Affected images versions

$ ls /lib/passwd
ls: cannot access /lib/passwd: No such file or directory
$ grep root /usr/etc/passwd
root:x:0:0:root:/root:/bin/ash

Users with UID>=1000 should not be

The ostree-convert-from-debian is supposed to split UID<1000 users into /lib/passwd and everything else into /usr/etc/passwd, but the call to split_passwd_files () is commented out.

/lib/passwd does not exist and /usr/etc/passwd ships the UID<1000 users.

It's something that has the potential to cause issues but which in practice we do not hit them at the moment.

This section is for management only, it should be the last one in the description.
