gst-libav-1.0: Link against a shared ffmpeg instead of static

We can't link to a static ffmpeg built with MinGW when gst-libav is
built with MSVC. Another big advantage of this is that people can
switch out the ffmpeg libs with their own DLLs, dylibs, etc when using
our binary builds without having to build from scratch with Cerbero.
