Subject: [PATCH] Fix possible integer overflow in WebM duration

The issue could lead to the MPD attribute mediaPresentationDuration being
wrongly generated for WebM streams with a duration longer than INT32_MAX.

The root-cause was that StreamInfo::set_duration() accepted an int instead of a
uint64_t. This seems like a pure typo, since StreamInfo already uses a uint64_t
internally for representing duration.
