modulejail v1.6.2

• mkinitcpio: strip the blacklist in the distro's single build (root cause
  diagnosed by @tjmnmk, #29). --install-initramfs-hook no longer installs a
  separate pacman trigger that ran a second full mkinitcpio -P after the
  distro's own kernel-install rebuild. Instead it drops
  HOOKS+=(modulejail-strip) into /etc/mkinitcpio.conf.d/, so the strip hook
  runs inside the distro's single build. This removes the wasted second build
  and the brief window where the freshly written initramfs still carried the
  blacklist, bringing Arch in line with dracut and initramfs-tools, which
  already participate in one build. Reinstalling over an older version removes
  the legacy 95-modulejail-strip.hook trigger, and --uninstall-initramfs-hook
  cleans up the new drop-in. Requires mkinitcpio 31+ (for conf.d drop-ins);
  older versions get a warning to add the hook to HOOKS by hand. Verified on a
  live Arch host (mkinitcpio 41): one build, the strip hook runs, and the
  blacklist is absent from the generated image.
