tests/fate/ac3: Make ac3-fixed-encode-2 bitexact across arches

Browse Source 
Don't use a 7.1 EAC3 input file for which our decoder is not
bitexact; instead just use the asynth-44100-8.wav file
which (as a 7.1 file) exhibits the same issue fixed by
1b3f4842c1.
(Either the encoder or the resampler are still not completely
bitexact, so we limit the number of frames output.)

Also switch to a framecrc test so that the output channel layout
is directly contained in the ref file.
