pkgtools/pkgchkxx: Update to 0.2.4

## 0.2.4 -- 2025-01-18

* `pkgrrxx -u` now displays a progress bar while checking for outdated
  packages, if `stderr` is a tty.
* Fix an issue where `pkgchkxx -u` can access invalidated memory and then
  crash. The bug was introduced at version 0.2.2. Reported by @ryoon [#9]
  and @0323pin [#10].
* Fix the formatting of `pkgchkxx` displaying commands to run. There was a
  space missing between time and command.
* Fix `pkgchkxx -un` not simulating the effect of `pkg_delete -r`. The same
  issue exists in the original `pkg_chk` but it'd be nice to fix it.
