Jilles Tjoelker ddd956b0b7 find: Include nanoseconds when comparing timestamps of files.
When comparing to the timestamp of a given file using -newer, -Xnewer and
-newerXY (where X and Y are one of m, c, a, B), include nanoseconds in the
comparison.

The primaries that compare a timestamp of a file to a given value (-Xmin,
-Xtime, -newerXt) continue to compare times in whole seconds.

Note that the default value 0 of vfs.timestamp_precision almost always
causes the nanoseconds part to be 0. However, touch -d can set a timestamp
to the microsecond regardless of that sysctl.
