Fixed issue with trailing dots in file paths

Paths such as the following were causing issues:
/tea/hottea/.
/tea/hottea/..

Unfortunately the existing structure for path lookup didn't make it very
easy to introduce proper handling in this case without duplicating the
entire skip logic for paths. So the lfs_dir_find function had to be
restructured a bit.

One odd side-effect of this is that now lfs_dir_find includes the
initial fetch operation. This kinda breaks the fetch -> op pattern of
the dir functions, but does come with a nice code size reduction.
