dirstate-v2: Apply SECOND_AMBIGUOUS to directory mtimes too
This would only be relevant in contrived scenarios such as a dirstate file
being written with a libc that supports sub-second precision in mtimes,
then transfered (at the filesystem level, not `hg clone`) to another
system where libc *doesn’t* have sub-second precision and truncates the stored
mtime of a directory to integer seconds.
