Remove flaky unit test VideoCaptureTest::AllocateSameCameraTwice

AllocateSameCameraTwice tested to open the same camera twice.
However, this is can not happen in Chrome since the VideoCaptureManager ensure this.
Further more, this have never worked on Mac and reasently have started to fail on Linux due to changes in the V4L2 driver behaviour.
