Remove <model>.pte generation from export_bundled_program.py (#714)

Summary:
Pull Request resolved: #714

Pull Request resolved: #692

Currently, this script generates two files:
- `<model>.pte` after calling `save_pte_program`
- `<model>.bp` after calling `save_bundled_program`

Since this example is intended to showcase the functionality of the bundled program, we shouldn't generate `<model>.pte` -- only `<model>.bp`.

We should also rename the function to reflect this.

Gasoonjia tarun292 do you agree w/ the above? Just a small thought I had while using this.
