wt-status.c:quote_path(): convert empty path to "./"

Now that we are correctly removing leading prefixes from files in git
status, there is a degenerate case: the directory matching the prefix.
Because we show only the directory name for a directory that contains
only untracked files, it gets collapsed to an empty string.

Example:

  $ git init
  $ mkdir subdir
  $ touch subdir/file
  $ git status
  ...
  # Untracked files:
  #   (use "git add <file>..." to include in what will be committed)
  #
  #       subdir/

  So far, so good.

  $ cd subdir
  $ git status
  ....
  # Untracked files:
  #   (use "git add <file>..." to include in what will be committed)
  #
  #

  Oops, that's a bit confusing.

  This patch prints './' to show that there is some output.
