compositor-x11: verify that detectable repeat was really set

Since the XKB says that support for detectable repeat is in fact
optional:
http://www.x.org/releases/current/doc/kbproto/xkbproto.html#Querying_and_Changing_Per_Client_Flags
we might as well be good citizens and check that it was really set. With
the X server this would never happen, though.
