[Buildroot] [PATCH 2/2] package/ffmpeg: fix static linking with alsa

[Bernd Kuhls]

If BR2_PACKAGE_ALSA_LIB_RAWMIDI is enabled ffmpeg needs also
BR2_PACKAGE_ALSA_LIB_SEQ to link against alsa.

A similar patch was committed to alsa-utils:
https://git.buildroot.net/buildroot/commit/package/alsa-utils?id=c69088b8c35177cecdd0f1f385c13f5b2c509f1d
