Subject: [PATCH] operations: fix making a directory with modtime asking twice
 with --interactive

MkdirModTime checked --interactive/--dry-run itself and then called
MkdirMetadata or Mkdir which check again, so --interactive asked twice
about making the same directory and --dry-run skipped before the
operation could be shown in the progress display or counted as a
check.

Now MkdirModTime decides how to make the directory first and delegates
entirely to MkdirMetadata, or Mkdir followed by SetDirModTime, each of
which does its own --interactive/--dry-run check exactly once. This
also means the modtime setting fallback shows in the progress display,
respects --no-update-dir-modtime and has its errors counted.
