baseparse: Disable building index table if upstream format is TIME

An index table of baseparse is being used when upstream failed
to handle seek event, and then baseparse tries BYTE format seeking
as a fallback. But upstream TIME format means that upstream
has responsibility of seek event handling.
Moreover, upstream TIME format seeking failure would imply
that BYTE format seeking will be also very unlikely successful.
