media_perception: Check D-Bus response for nullptr.

Add a check for nullptr at the beginning of the
HandleFalconPtzTransitionResponse callback.
http://google3/third_party/chromiumos_libchrome/dbus/object_proxy.h?l=134
provides that nullptr can be passed to the callback if the method call
(DoPTZTransition) was unsuccessful.

Also copied google3/videoconf/gvc2/rtanalytics/cros_proto/huddly.proto
to proto/huddly.proto.

BUG=b:170953648,chromium:1152909
TEST=Deployed local builds of MPS to endeavour. Without this patch,
camera crashes occasionally produce MPS crashes with the stack trace
ending in dbus::PopArrayOfBytes; with this patch, camera crashes
generally do not produce MPS crashes.
