Add common methods to detect if tracefs and user_events is enabled. If either is not enabled skip the test. If tracefs is enabled, but is not mounted, mount tracefs and fail if there were any errors. Fail if not run as root.
This will leave tracefs mounted if it was not already mounted which is a change to the system configuration. While that may happen if things go wrong during a test we should probably avoid actively doing this and either only skip or try to umount at the end of the test if we mounted ourselves.
