perf c2c: Use stdio interface if slang is not supported
If the slang lib is not installed on the system, perf c2c tool disables TUI mode and roll back to use stdio mode; but the flag 'c2c.use_stdio' is missed to set true and thus it wrongly applies UI quirks in the function ui_quirks(). This commit forces to use stdio interface if slang is not supported, and it can avoid to apply the UI quirks and show the correct metric header.
