[roll] Roll fuchsia [audio_core] temporary 4->2 channel-mapper

As a short-term device-specific workaround, the SourceReader class
that provides channel mapping from 4-channel to 2-channel has been
changed to simply copy channels 0 and 1 as-is, ignoring channels
2 and 3. Previous behavior was to emit the average of input channels
0 and 2 as output channel 0, and the average of input channels 1 and
3 as output channel 1.

We expect this workaround to be removed once the driver is updated for
the device in question. This is tracked with fxb/85201.

Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance via the IRC channel #fuchsia on Freenode.

Obtaining the source

First install Jiri.

Next run:

$ jiri init
$ jiri import minimal https://fuchsia.googlesource.com/integration
$ jiri update

Third party

Third party projects should have their own subdirectory in ./third_party.
