Fix error applying new stdout settings

Browse source 
On Fedora 26 tio will quit with the following error message:

"Error: Could not apply new stdout settings (Invalid argument)"

In case of Fedora, it turns out that the new stdout settings used are a
bit too agressive because an empty termios structure is used. To remedy
this we reuse the existing stdout settings and only reconfigure the
specific options we need to make a "raw" stdout configuration.
