scripts: west_commands: runners: Fix default value for --dt-flash

The '--dt-flash' parameter accepts a string like "y", "yes", "no", etc,
and is supposed to be converted into a boolean value. This is only the
theory as in practice, the default value is set to 'n' and is never
converted to False afterwards.

Set the default value to False.
