Anton Khirnov c6ae560a18 lavf/framecrcenc: do not hash side data
There are no guarantees that all side data types have the same
representation on all platforms.

Tests that change output due to this:

id3v2-priv-remux, cover-art-mp3-id3v2-remux, gapless-mp3: SKIP_SAMPLES,
which is tested by fate-gapless-mp3-side-data

matroska-vp8-alpha-remux: MATROSKA_BLOCKADDITIONAL, which is tested by
remux itself (side data is written into output)

matroska-mastering-display-metadata: MASTERING_DISPLAY_METADATA and
CONTENT_LIGHT_LEVEL, which are tested by ffprobe invocation in the same
test

matroska-spherical-mono-remux: STEREO3D and SPHERICAL, which are tested
by ffprobe invocation in the same test

segment-mp4-to-ts: MPEGTS_STREAM_ID, which is tested by ts remuxing
tests

webm-webvtt-remux: WEBVTT_IDENTIFIER/SETTINGS, which is tested by the
ffprobe invocation in the same test

mxf-d10-user-comments: CPB_PROPERTIES, which is tested by mxf-probe-d10

mov-cover-image: SKIP_SAMPLES, which is tested for mov by
mov-aac-2048-priming

copy-trac3074: AUDIO_SERVICE_TYPE, which is tested by fate-hls-fmp4_ac3
