Ahmet Alp Balkan 48d8757700 integration-cli: use cmd.Stdin instead of cat/tee for TestExportContainerAndImportImage
os.Exec("bash", "-c", dockerBinary) ends up making a call like
bash -c c:\...\docker.exe on windows msys shell, which does not work.

This test makes use of exec.Command.Stdin to pass image back to
docker import.

- Upside: fixes the test on windows
- Downside: cat/tee compatibility is no longer tested in this test case
