build/vdpau: drop support for dynamic loading of libvdpau

Browse Source 
After a recent library update on my system MPlayer started crashing on
exit in XCloseDisplay() if -vo vdpau had been used. With normal
linking it works OK. Since there should be little need for the dynamic
loading functionality any more, I'll just drop it rather than try
investigating the exact problem with dynamic loading and whether it
would be fixable. VDPAU is now linked normally with -lvdpau if
available.
