ftrace: report ftrace clock in the trace On devices with ancient kernels (e.g. 3.xx) the ftrace "boot" clock is not available (Even though CLOCK_BOOTTIME) does exist. When that happens, report the actual clock being used in the trace so we can clock sync at import time. Bug: 195428830 Change-Id: I72ee62be7c5e3c0b6563e26cf4d886206e45cdda
