dir.c: git-status --ignored: don't list files in ignored directories

'git-status --ignored' lists both the ignored directory and the ignored
files if the files are in a tracked sub directory.

When recursing into sub directories in read_directory_recursive, pass on
the check_only parameter so that we don't accidentally add the files.
