Unreliable determination of nv_jetson_model in run.sh - fixed

[TangmereCottage]

In run.sh,

jetson-containers/run.sh

Line 307 in eb2e184

cat /proc/device-tree/model > /tmp/nv_jetson_model

cat is used to generate a file containing the model descriptor in /tmp/nv_jetson_model. The problem is that if that file is not found, the run.sh command creates a new folder, which then hoses the AI, such as nano_llm, due to "failed to find/open file /proc/device-tree/model" (which makes sense because it's not a file but a folder).

The bug is sort of tricky because once the folder has been created by a broken cat command, subsequent invocations of run.sh will not remove it and your stack will remain broken.

Solution:
Make sure that /tmp does not erroneously contain a folder called "nv_jetson_model". If there is one, manually delete it.
