flacdec: allocate sample buffers with av_malloc
...
The buffers are only allocated once, although it can happen from
any of a few different places, so there is no need to use realloc.
Using av_malloc() ensures they are aligned suitably for SIMD
optimisations.

flag, which appears necessary to playback corePNG P-frames.
