scripts/combo-layer: Fix exit codes and tty handling
If combo-layer is called from a non-interactive context we should exit with a correct error code rather than try and drop to a shell. This patch cleans up a few error case exit codes as well as detecting and handling non-interactive usage. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
