logd: regression in handling watermark boundary.
(cherry pick from commit a354d42ec18f59a466b7ac57e456b1860e9e4f85)
Deal with a regression introduced in commit
da1b4a18bbb3867ff71ff2b998b7d579e3ab2462 (logd: drop mSequence from
LogBufferElement) where log_time was compared against nsec() time
miscalculating the watermark boundary. When dealing with logcat
-t/-T, or any tail reading, add a margin to prune to back off by a
period of 3 seconds (pruneMargin).
Test: gTest liblog-unit-tests logcat-unit-tests and logd-unit-tests
