Make ExtractorSampleSource constructor consistent.

The allocator and buffering policy (e.g. how large the buffer
is) is moving to the top level as part of playlist support,
so it no longer makes sense to inject these parameters as
args into ExtractorSampleSource's constructor.

Instantiating the allocator and buffer size inside of the
source is temporary and only until they're moved up.
