[Error] exported_bins does not work for rootful containers

[kerneis-anssi]

Describe the bug

Adding an exported_bins line to a distrobox assemble ini file where root=true yields an error.

To Reproduce

$ cat << EOF > test.ini
[test]
image=fedora:latest
root=true
exported_bins=/usr/bin/ls
EOF
$ distrobox assemble create --file test.ini
 - Creating test... 
Creating 'test' using image fedora:latest	 [ OK ]
Distrobox 'test' successfully created.
To enter, run:

distrobox enter --root test

Error: no such container test
Create it now, out of image registry.fedoraproject.org/fedora-toolbox:38? [Y/n]: n
Ok. For creating it, run this command:
	distrobox create <name-of-container> --image <remote>/<docker>:<tag>
Error: no such container test
Create it now, out of image registry.fedoraproject.org/fedora-toolbox:38? [Y/n]: n
Ok. For creating it, run this command:
	distrobox create <name-of-container> --image <remote>/<docker>:<tag>

The problem is that the enter and export commands that are run after create by assemble miss the --root flag, so the container is looked up in the non-root list of containers, where it doesn’t exist.

Expected behavior

The commands started implicitly by distrobox assemble for containers with root=true should have the --root flag.
