check-ignore: convert to use parse_pathspec

Browse source 
check-ignore (at least the test suite) seems to rely on the pattern
order. PATHSPEC_KEEP_ORDER is introduced to explictly express this.
The lack of PATHSPEC_MAXDEPTH_VALID is sufficient because it's the
only flag that reorders pathspecs, but it's less obvious that way.
