Revert "basesrc: Send an update NEWSEGMENT event downstream if the duration changes"

Browse source 
This reverts commit 934faf163c.

Original commit leads to possibly sending newsegment event downstream
in pull mode.  In push mode, quite some downstream elements
are likely to only expect newsegment event following a seek they performed
and as such may have their state messed up.
