Subject: [PATCH] xtensa-build-zephyr.py: show symbolic links at the end

Not sure why I thought it would be complicated; I should have done this
much sooner.

Before:

```
build-sof-staging
|-- sof
|   +-- intel
|       +-- sof-ipc4
|           |-- adl
|           |   +-- community
|           |       +-- sof-adl.ri
|           |-- adl-n
|           |   +-- community
|           |       +-- sof-adl-n.ri
|           |-- arl
|           |   +-- community
|           |       +-- sof-arl.ri

```

After:

```
build-sof-staging
|-- sof
|   +-- intel
|       +-- sof-ipc4
|           |-- adl
|           |   +-- community
|           |       +-- sof-adl.ri  -> ../../tgl/community/sof-tgl.ri
|           |-- adl-n
|           |   +-- community
|           |       +-- sof-adl-n.ri  -> ../../tgl/community/sof-tgl.ri
|           |-- arl
|           |   +-- community
|           |       +-- sof-arl.ri  -> ../../mtl/community/sof-mtl.ri

```
