[video_player] Skip flaky tests in certain circumstances on Android (flutter#5872)

Temporary workaround for flutter#141145

This doesn't fully skip the test because this problem doesn't happen in CI device tests or locally, so rather than totally lose coverage this detects the very specific markers of this flake and skips only when that happens. This should allow the tree to stop being so red with the minimal coverage loss while we investigate this further.

Part of flutter#141145
