report_path_error(): move to dir.cjc/report-path-error-to-dir

The expected call sequence is for the caller to use match_pathspec()
repeatedly on a set of pathspecs, accumulating the "hits" in a
separate array, and then call this function to diagnose a pathspec
that never matched anything, as that can indicate a typo from the
command line, e.g. "git commit Maekfile".

Many builtin commands use this function from builtin/ls-files.c,
which is not a very healthy arrangement.  ls-files might have been
the first command to feel the need for such a helper, but the need
is shared by everybody who uses the "match and then report" pattern.

Move it to dir.c where match_pathspec() is defined.
