seat: allow clients to bind to seat multiple times

Browse source 
This lets clients bind to a seat multiple times by re-using the existing
wlr_seat_client whenever a duplicate request happens.
Previously, an independant wlr_seat_client would be created and only
events from one would be processed.

Fixes #1023.
