dri: Avoid swapbuffer throttling in glXCopySubBufferMESA

Browse Source 
We were supplying __DRI2_THROTTLE_SWAPBUFFER, rather than the obvious
choice of __DRI2_THROTTLE_COPYSUBBUFFER.  This meant that we hit the
swap-based frame throttling.  glXCopySubBuffer doesn't seem like it's
intended to be a frame boundary, so we'd like to avoid this throttling.
