sd_lavc_conv: don't check AV_CODEC_PROP_TEXT_SUB flag

Browse Source 
Not actually useful. This would break whenever a new text subtitle
format would be added, which requires a binary->text transformation.
(mov_text is one such format; disable it.) In general, we would have
to know which packet formats are binary, which we don't, so the only
reasonable way to handle this is a white list.
