FYI: error on write failure with --version/--help

[Ralf Wildenhues]

As seen on automake-patches..

Against branch-1-5 below, against branch-2-0/HEAD attached.
(I thought it was useful to have errors for --config and --features as
well.)

Regards,
Ralf

        * ltmain.in, libtoolize.in: Exit with nonzero status on write failures
        with --help or --version or, in case of ltmain, --config or --features.
