[mythtv] [patch] adjust PreviewPixmapOffset for RecordPreRoll

[Lucas Meijer]

This patch adds RecordPreRoll seconds to the PreviewPixmapOffset used to 
generate a preview image for a recording.

Its not 100% foolproof, since it uses the current recordpreroll setting, 
and there is a possibility that the recording was made with a different 
setting. Still better than before IMO, as RecordPreRoll wasn't taken 
into account at all.
