match_pathname(): drop unused "flags" parameter

This field has not been used since the function was introduced in
b559263216 (exclude: split pathname matching code into a separate
function, 2012-10-15), though there was a brief period where it was
erroneously used and then reverted in ed4958477b (dir: fix pattern
matching on dirs, 2021-09-24) and 5ceb663e92 (dir: fix
directory-matching bug, 2021-11-02).

It's possible we'd eventually add a flag that makes it useful here, but
there are only a handful of callers. It would be easy to add back if
necessary, and in the meantime this makes the function interface less
misleading.
