dir.c: refactor is_path_excluded()

Browse Source 
In a similar way to the previous commit, this extracts a new helper
function last_exclude_matching_path() which return the last
exclude_list element which matched, or NULL if no match was found.
is_path_excluded() becomes a wrapper around this, and just returns 0
or 1 depending on whether any matching exclude_list element was found.

This allows callers to find out _why_ a given path was excluded,
rather than just whether it was or not, paving the way for a new git
sub-command which allows users to test their exclude lists from the
command line.
