vo_opengl: use GL_CLIENT_STORAGE_BIT for DR 

mesa won't pick client storage unless this bit is set, and we
*absolutely* want to be using client storage for our DR PBOs.
Performance is shit on AMD otherwise. (Nvidia always uses client storage
for persistent coherent buffers whether you tell it it or not, probably
because it's way faster and nvidia doesn't trust users to figure that
out on their own)
