Colin Walters b797a42f3e core,kernel: Set up /etc/passwd for dracut
This fixes a longstanding spew of error messages from the initramfs
because we don't have nss-altfiles set up there.  Rather than
trying to do it, just do the dance of re-synthesizing `/etc/passwd`
as it traditionally looks around running dracut, the same as we
do for scripts during core layering.

Yes, this is all a mess and hopefully I'll get to sysusers soon...
