vaapivideobufferpool: remove GL_TEXTURE_UPLOAD_META
vaapivideobufferpool: remove GL_TEXTURE_UPLOAD_META

Since gstreamer-vaapi is coupled with gstreamer releases, there is no need to
keep compatibility definition.

This patch removes the definition of
GST_BUFFER_POOL_OPTION_VIDEO_GL_TEXTURE_UPLOAD_META since it is in
gst-plugins-base version 1.2.2
