glx: fix regression with copy sub buffer disappearing

So copy sub buffer isn't a core extensions it's a driver extension
which means we are using totally the wrong interface to query for it
here, which means bad things happen when you roll out this code,
for instance MESA_copy_sub_buffer stops working.

This is just the hack I'm sticking in Fedora to avoid the regression
for now, but hopefully will inspire us.
