build(rpm): declare all seven FFmpeg pkg-config modules, not three

Browse Source 
`ffmpeg-next` is pulled with default features, so `ffmpeg-sys-next`'s build script
pkg-config-probes codec/device/filter/format/util/resampling/scaling and panics on
the first one missing. The spec named three.

RPM Fusion's `ffmpeg-devel` ships all seven in one package, which hid it. On a host
where those three instead resolve to Fedora's split `libav*-free-devel` packages,
`dnf builddep` installs exactly three and the build dies in a build script:

    The system library `libavfilter` required by crate `ffmpeg-sys-next` was not found.
