archr: package scripts and alpm hooks so they ship through pacman

The archr scripts (archr-update, archr-flash-sync, archr-depmod,
wifictl, governors, ...) and the alpm hooks were installed in
post_install, which writes into the assembled image only, so they never
entered the pacman package: every one of them was flash-only. That is
why the dual update path could deliver package contents but not its own
plumbing, and the depmod fix would not have reached existing installs.
Move the copy into makeinstall_target so the package carries them and
pacman -Syu updates them like anything else.
