FFmpeg doesn't build with default_library=shared

While trying to build FFmpeg wrap and setting default_library=shared I get errors during the makedef step:

FAILED: subprojects/FFmpeg/avutil.def

I don't have the required permissions to fork and do a proper MR, so if a maintainer could verify and apply the following patch (or equivalent) that would be nice:

Subject: [PATCH] meson: add missing os argument to makedef

without this, ffmpeg was failing to build with "default_library=shared".
