scripts/poky-qemu-internal: call stty sane before exit 

When qemu is booted into console with -nographics
then after exiting the terminal line settings are messed
up. This patch calls stty sane to restore the terminal
settings to default.

stty is part of coreutils which is installed on all
host distros hence there is no need to warn about it
being available or not
