dir.c: Make git-status --ignored more consistent

The current behavior of git-status is inconsistent and misleading.
Especially when used with --untracked-files=all option:

 - files ignored in untracked directories will be missing from
   status output.

 - untracked files in committed yet ignored directories are also
   missing.

 - with --untracked-files=normal, untracked directories that
   contains only ignored files are dropped too.

Make the behavior more consistent across all possible use cases:

 - "--ignored --untracked-files=normal" doesn't show each specific
   files but top directory.  It instead shows untracked directories
   that only contains ignored files, and ignored tracked directories
   with untracked files.

 - "--ignored --untracked-files=all" shows all ignored files, either
   because it's in an ignored directory (tracked or untracked), or
   because the file is explicitly ignored.
