[Error] Distrobox links

**Describe the bug**
Distrobox wrongfully links libdirectfb_nvidia.so. Installing libdirectfb in guest fails due to the already existing symlink.

**To Reproduce**
Install gstreamer1.0-plugins-bad on your host.
Create a 24.04 ubuntu container.
Try installing gstreamer1.0-plugins-bad.

**Expected behavior**
Being able to install gstreamer1.0-plugins-bad and especially its dependency libdirectfb.

**Logs**
Apt shows:

這個 issue 是關於在 Ubuntu 容器中安裝 libdirectfb 時發生的 symlink 衝突。先檢查 Distrobox 如何處理主機到容器的函式庫連結，尤其是與 NVIDIA 相關的函式庫。查看 Distrobox 原始碼中的連結邏輯以及 'Invalid cross-device link' 錯誤。按照 issue 中的步驟重現這個 bug，然後檢查 symlink 是如何建立的，以及它為什麼會與套件安裝發生衝突。
