#9192: CC608 "clear display" codes are not processed correctly

EIA-608 closed captions are being displayed too long (usually until the
caption changes). This isn't usually a big problem except for cases where
the captioner has explicitly cleared the captions to avoid obscuring some
on-screen graphic.
I think this problem was introduced when the OSD was ported to MythUI. In
CC608Reader::Update, the captions should be cleared when "subtitle.clr ==
0 && subtitle.len == 0". However, SubtitleScreen::DisplayCC608Subtitles
does not update the display when this happens.
The attached patch seems to fix the problem.
