Imagenet inference to nightly fix (#16599)

* split to cd and shell

* comment

* lots of prints

* copy binary at correct location

* remove comments

* add mkl lib

* update docker run build function

* set nvidia docker true to run imagenet inference on GPU

* Revert "set nvidia docker true to run imagenet inference on GPU"

This reverts commit 98f8eef.
As we don't need GPU for compilation.
