lib/xiph/OggSyncState: increase skip limit yet again to 1 MB

More like 70bd35a and
a757eeb

This allows skipping through large OpusTags pages.

Of course, there must be a limit, and a higher limit means we waste
more I/O to detect that there is really just garbage, but these days,
reading through 1 MB garbage seems acceptable.
