[Fontconfig] [PATCH] Update stream position after seeking is done

[Akira TAGOH]

Thanks for reminding me. changed like FT_Stream_Seek deals with.

BTW I think posting patches here would be a good idea to make the code
visible for reviews though, it's a bit hard to keep it on track.
particularly there are no time to have a look at it. so I'd recommend
to file a bug to bugzilla too.
I'm also pondering to change the initial bug owner to the list (maybe
a separate list like fontconfig-bugs?) and open to watch bugs if one
prefer :)
