Ole André Vadla Ravnås ebd2a6d6e9 applemedia: don't push synchronously from callback
The codec that called us might be holding locks to shared resources, so
we should never push downstream from within its buffer callback.

Note that a GstBufferList is not used here because we need to preserve
the buffer metadata held by our GstBuffer subclasses.
