plugins/elements/gsttypefindelement.c: Move detecting the input caps of the sinkpad to the setcaps function.

Browse source 
Original commit message from CVS:
* plugins/elements/gsttypefindelement.c:
(gst_type_find_element_have_type), (gst_type_find_element_init),
(gst_type_find_element_setcaps), (gst_type_find_element_chain):
Move detecting the input caps of the sinkpad to the setcaps function.
This allows us to update the output caps when we receive new input caps
instead of always using the first detected caps.
