scripts/runfvp: add Screen support

Browse Source 
Add support for Screen the GNU terminal multiplexer. The -t/--terminal
option now accepts "screen" as a terminal type. When selected, the tool
must be run from within an existing Screen session, and each FVP
terminal is opened in a new Screen window.

Use `screen -ls` to view the list of currently attached sessions.
The default terminal can also be configured by writing a [INI-style][INI] configuration file to `~/.config/runfvp.conf`:
