Verifying the change for base-files in resolute following the testplan:
Launching a fresh resolute container:
```
$ lxc launch ubuntu:resolute base-files-resolute
Launching base-files-resolute
$ lxc exec base-files-resolute -- su - ubuntu
ubuntu@base-files-resolute:~$
```
1. Confirming that the multilib dir is absent (all report No such file
or directory):
```
ubuntu@base-files-resolute:~$ ls -ld /usr/lib32 /usr/libo32 /usr/libx32 /lib32
/libo32 /libx32
ls: cannot access '/usr/lib32': No such file or directory
ls: cannot access '/usr/libo32': No such file or directory
ls: cannot access '/usr/libx32': No such file or directory
ls: cannot access '/lib32': No such file or directory
ls: cannot access '/libo32': No such file or directory
ls: cannot access '/libx32': No such file or directory
```
2. Reproducing with the current version:
```
ubuntu@base-files-resolute:~$ apt policy base-files

As expected, dpkg fails with

3. Enabling `-proposed` and upgrade:
```
ubuntu@base-files-resolute:~$ sudo apt install -t resolute-proposed base-files

As expected, the output reports `Removing dangling /lib... symbolic link.`
and the new version is installed:
```
ubuntu@base-files-resolute:~$ dpkg -s base-files | grep Version
Version: 14ubuntu6.3
ubuntu@base-files-resolute:~$ ls -ld /lib32 /libo32 /libx32
ls: cannot access '/lib32': No such file or directory
ls: cannot access '/libo32': No such file or directory
ls: cannot access '/libx32': No such file or directory
```
As expected, "No such file or directory" for all three
4. Regression check, valid symlink kept and trigger still works:
```
ubuntu@base-files-resolute:~$ sudo apt install libc6-i386
ubuntu@base-files-resolute:~$ ls -ld /usr/lib32 # directory exists
drwxr-xr-x 1 root root 550 Oct 23 12:39 /usr/lib32
ubuntu@base-files-resolute:~$ readlink /lib32 # -> usr/lib32 (created by the
base-files trigger)
usr/lib32
ubuntu@base-files-resolute:~$ sudo apt install --reinstall base-files

As expected, the install succeeds, NO `Removing dangling` message is
printed.
```
ubuntu@base-files-resolute:~$ readlink /lib32 # still -> usr/lib32
