Subject: [PATCH] flatpak-run: Unset VK_DRIVER_FILES and VK_ICD_FILENAMES

These environment variables inform the Vulkan loader on where to find driver files.
Since they typically point to locations on the host filesystem, any application that
attempts to load Vulkan within the flatpak sandbox would break with these set.

(cherry picked from commit b8d8d80c611c4e50946ca0e31332843b496ed57e)
