`ouch list` should show symlink targets for supported formats

[marcospb19]

Take this example.tar example:

$ ouch l example.tar
Archive: "example.tar"
example
example/file
example/link

$ ouch l example.tar --tree
Archive: "example.tar"
└── example
   ├── file
   └── link

The expected output:

$ ouch l example.tar
Archive: "example.tar"
example
example/file
example/link -> target_here

$ ouch l example.tar --tree
Archive: "example.tar"
└── example
   ├── file
   └── link -> target_here
