Message : Fix info collection on Android without Vulkan. Allows Vulkan info collection even if Vk is not enabled in ANGLE. Also removes the system_utils error message so that the Android test runner can parse the standard output without conflicts. Bug: chromium:1133459 Bug: angleproject:5109 Change-Id: I7d7bff0f1c3e456342f27538812b33ee6cd1054b Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2436657 Reviewed-by: Cody Northrop <cnorthrop@google.com> Reviewed-by: Jamie Madill <jmadill@chromium.org> Commit-Queue: Jamie Madill <jmadill@chromium.org>
