vo_opengl: load certain EGL extensions needed for VAAPI EGL interop

These extensions use a bunch of EGL types, so we need to include the EGL
headers in common.h to use our GL function loader with this.

In the future, we should probably require presence of the EGL headers to
reduce the hacks. This might be not so simple at least with OSX, so for
now this has to do.
