This patch changes gst-ffmpeg to use av_picture_copy instead of swscale to copy
pictures, using swscale to simply copy pictures is way overkill.

Note that with this patch the linking of libgstffmpeg.so to libswscale isn't
needed anymore AFAIK, so that probably can be removed too.

Besides saving the overkill of swscale to simply copy the picture this alsso
works around a bug in some version of swscale, which is exposed by using the
system ffmpeg on Fedora. Normally I wouldn't dare mentioning the use of a
system ffmpeg, but I'm very happy to see system ffmpeg related patches were
accepted into 0.10.4 and that 0.10.4 now works well with newer ffmpeg
snapshots.
