fdkaacdec: Support up to 5 rear channels

Browse source 
The `switch (n_rear)` supports up to 5 rear channels, but our channel
set only had space for 3. Size the set properly to fix this.

This didn't actually cause any memory unsafety as `PUSH_CHAN` would stop
incrementing `n_rear` if the channel set is already full.

Thanks to @alatiera for noticing this.
