contentenc: use sync.Pool memory pools for encryption
We use two levels of buffers: 1) 4kiB+overhead for each ciphertext block 2) 128kiB+overhead for each FUSE write (32 ciphertext blocks) This commit adds a sync.Pool for both levels. The memory-efficiency for small writes could be improved, as we now always use a 128kiB buffer.
