There is an incompatibility in the serialization of shared memory handles
between the Mojo libraries used in Chromium vs. the older ones used in
ChromiumOS. As a workaround, this CL allows clients of the video capture service
to ask it to use raw file descriptors for sharing shared memory handles instead.
Note, this is only supported on platforms that use file descriptors for
base::SharedMemoryHandle, i.e. Posix platforms.
