Fix unused lambda captures in //device and //services/media_capture.

Fix unused lambda captures in //device and //services/media_capture.

Clang just got a new warning about unused lambda captures,
and that requires us to clean all places with this issue
across all the Chromium code base. This CL fixes all such
cases in //device and //services/media_capture.

An example of a code that is no longer considered normal is

auto g = [i, j]() { printf("%d\n", i); };

in which j is never used in the lambda and therefore its capture is unnecessary.
