Should increase coverage of some decoders.

Passing 6 to av_get_default_channel_layout() will return the 5.1 layout but
never 5.1(side), which is for example what the dts decoder actually looks for.
Any suggestion on how to make the fuzzer pick one of the non default layouts
using a given amount of channels?
