Bug#758374: x264: Use pkg-config to determine FFmpeg linker flags

Dear maintainer,

I am working on reintroducing FFmpeg to Debian [1-2].

In order to make FFmpeg co-installable with Libav, the libraries were
renamed to lib*-ffmpeg. Thus using linker flags like '-lavcodec' doesn't
work with the FFmpeg packages.

To get the correct linking flags for both FFmpeg and Libav, one can
(and should) use pkg-config.

Attached patch achieves that for this package, by simply build-depending
on pkg-config. Please apply it to facilitate building your package with
FFmpeg in Debian.

If you want to facilitate this even further, you can also add
lib*-ffmpeg-dev alternatives to the Libav build-dependencies.

While the FFmpeg package is still waiting in the NEW queue [3], it can
already be built from the git repository [4].

Best regards,
Andreas
