is_dot_or_dotdot() verifies if the name of the directory sent as parameter to this function is the same with '.' or '..' and returns 0 if that is true.
There is unnecessary to iterate each character of the char* argument and verify it with strcmp because if there is a match that is at the beginning of chars.
