[ffmpeg] Temporarily disable -Wconversion warnings

While working on adding the `hwasan` variant, I unknowingly started
building ffmpeg since it's not yet in the list of variants that can use
a prebuilt binary. This temporarily disables -Wconversion to unblock
this work and some `fx format-code` changes.
