Remove the pacman hook

Status bars already drop installed entries, and the path unit covers repo
builds, so the hook only ran checkupdates on every transaction.

-Building into a local repository (`aur build`, `aur sync`) doesn't run pacman, so the hook can't catch it. To run `update-notify --quiet` whenever a repository changes, add the repository files to watch to `update-notify.path`:

 `threshold` is the minimum number of updates (repo + AUR) before update counts are shown. It overrides the `THRESHOLD` setting below for that run's notification only; the pending file keeps the configured value.

-The file reflects the last run, which the pacman hook and `update-notify.path` keep close to current. To keep a bar current in between, drop entries whose installed version (`pacman -Q`) is no longer older than `newver`, or, for `kernel` lines, whose custom build has caught up with `stock-ver` (ignoring `pkgrel`). This only reads local data, so it's cheap to run often.
