Subject: Link the video plugin statically into the main binary on OS X.

This makes the OS X build more robust and should help pave the
way for the integration of the video plugins as well as LTO.

There are now no more global class level namespace conflicts left,
as evidenced by the fact that Dolphin can be linked with -all_load,
not that you would want to.
