shell/macOS: Remove backslashes from the extension display name

Tell cmake not to escape shell strings adding backslashes before
spaces by passing the VERBATIM optiton. Also add the quotes to
whole command line arguments to prevent quotes from appearing on the
XCode side, because of the VERBATIM option.

This only affects themed clients since the default theme doesn't
have space in its APPLICATION_NAME.
