lavfi/tests: Fix 16-bit vf_blend test to avoid memory not aligned to 2 bytes
Generic C implementation of vf_blend performs reads and writes of 16-bit elements, which requires the buffers to be aligned to at least 2-byte boundary. Also, the change fixes source buffer overrun caused by src_offset being added to to test handling of misaligned buffers. Fixes: #7226 Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
