Config TTY on startup

When a device boots with factory install shim, the default TTY
configuration has output post processing disabled. This results in
missing carriage return.

This change adds a step in factory install script to configure TTY
properly.

BUG=chrome-os-partner:18376
TEST=Boot factory install shim and netboot image, and see screen output
is fine.
