os.listdir() doesn't return entries for . or .., so we don't need to check for them here.

See https://docs.python.org/3/library/os.html#os.listdir

Return a list containing the names of the entries in the directory given by path. The list is in arbitrary order, and does not include the special entries '.' and '..' even if they are present in the directory.

`os.listdir()` doesn't return entries for `.` or `..`, so we don't need to
check for them here.

LGTM; confirmed that both implementations of listdir explicitly elide . and .., and it doesn't look like self._accessor.listdir can be anything other than os.listdir.
