Remove ui_out_flag::unfiltered_output

There is no longer any need for ui_out_flag::unfiltered_output --
nothing ever sets this flag.  This used to be needed to make the
_unfiltered output work, but now only printf_unfiltered can be used,
and it uses the puts_unfiltered method.  This patch removes the flag
and the dead code.
