Capture/Replay: Add suffix to label for test file search When tests are run with a wildcard filter on the backend, e.g. "TEST/ES2_Vulkan*" the same tests from different backends may end up in the same trace file directory, e.g. TEST_ES2_Vulkan and TEST_ES2_Vulkan_SwiftShader. So far, when searching for the ES2_Vulkan trace files the check for trace files would them also pick up all the _SwiftShader files, and the skript would assume that the file count is wrong and skip the replay. By adding "_capture" the start of the commonly used suffix, this is avoided and replays are no longer skipped because mis-counting capture files.
