/var/lib/warewulf/chroots/overlay directory should be somewhere else.

Steps to reproduce

[root@micropterus chroots]# ls
rocky-9  rocky-9-minimal
[root@micropterus ~]# wwctl container shell rocky-9
[rocky-9] Warewulf> exit
exit
+ LANG=C
+ LC_CTYPE=C
+ export LANG LC_CTYPE
+ dnf clean all
0 files removed
Rebuilding container...
Created image for VNFS container rocky-9: /var/lib/warewulf/provision/container/rocky-9.img
Compressed image for VNFS container rocky-9: /var/lib/warewulf/provision/container/rocky-9.img.gz
[root@micropterus chroots]# ls 
overlays  rocky-9  rocky-9-minimal
[root@micropterus chroots]# tree overlays/
overlays/
├── lower
├── nodeoverlay
└── work

3 directories, 0 files

Not sure what this overlay directory does or what triggers it to be created, but it breaks the assumption that everything in /var/lib/warewulf/chroots will be a node image chroot.

@mslacken can you look into this? I'd like to try to get a fix for this in v4.5.1 if possible.

Yes this are workdirs for the chroot process, especially if you the --render $NODENAME option, I will make a PR which removes them.
