fix(cli): Fixes errors on command output, closes #8110

[olivierlemasle]

Command output was fixed in #8042; however it also created two issues:

tauri/tooling/bundler/src/bundle/common.rs

Lines 183 to 194 in ae75004

	std::thread::spawn(move || {
	let mut line = String::new();
	let mut lines = stderr_lines_.lock().unwrap();
	loop {
	line.clear();
	if let Ok(0) = stderr.read_line(&mut line) {
	break;
	}
	debug!(action = "stderr"; "{}", &line[0..line.len() - 1]);
	lines.extend(line.as_bytes().to_vec());
	}
	});

• If read_line returns Err (which happens if the stream contains an invalid UTF-8 character), line is empty and &line[0..line.len() - 1] fails (attempt to subtract with overflow)
  That happens on macos with bundle_dmg.sh when the product name contains a Chinese character or an emoji (cf "--verbose" parameter cause "cargo tauri build" error #8110).
• If the stream ends with no linebreak (just EOF), line does not end with \n. Therefore, the last byte of the stream is removed. If this is e.g. an ASCII character, it's just one character missing in the output. If the last character is multi-bytes, it throws an error (byte index xxx is not a char boundary; it is inside xxx)
