Camera ITS: Fix test_multi_camera failed

In case a physical camera that contains only DEPTH information is
included in a logical camera, evaluating the DEPTH camera is
inappropriate because depth only camera doesn't have
backward-compatible capability.
However, this test does not check backward-compatible capability,
and the test fails due to unmatched yuv size.
To avoid the test failed, adding check for backward-compatible
capability is necessary.
