[nnpkg-run] set default backend using OP_BACKEND_ALLOPS environment var. (#8003)

`nnpackage-run` (in short, `nnpkg-run`) uses `nnfw_session` from nnfw APIs.
It uses GeneralConfigSource. It means we need to set configuration using nnfw APIs.
Thus, it reads from environment var and set default backends.
