store: optimize _pathencode by checking the length of the unencoded path

If the input path is already longer than _maxstorepathlen, then we can skip
doing the basic encoding (encodedir, _encodefname and _auxencode) and directly
proceed to the hashed encoding. Those encodings, if at all, will make the path
only longer.
