.gitignore: update the command to check tracked files being ignored

Recent git versions do not accept the noted command.

  $ git ls-files -i --exclude-standard
  fatal: ls-files -i must be used with either -o or -c

The -c was implied before, but we need to make it explicit since
git commit b338e9f66873 ("ls-files: error out on -i unless -o or -c
are specified").

Also, replace --exclude-standard with --exclude-per-directory=.gitignore
so that everyone will get consistent results.

git-ls-files(1) says:

  --exclude-standard
      Add the standard Git exclusions: .git/info/exclude, .gitignore in
      each directory, and the user's global exclusion file.

We cannot predict what is locally added to .git/info/exclude or the
user's global exclusion file.

We can only manage .gitignore files committed to the repository.
