Add archiso initramfs hooks so the live ISO can switch root

Browse source 
The profile shipped boot configs and the package list but lacked the
mkinitcpio archiso configuration, so mkarchiso built a stock initramfs
with no archiso hook. At boot the kernel honoured archisosearchuuid/
archisobasedir but nothing knew how to find and mount airootfs.sfs, so
switch-root failed and the live medium dropped to emergency mode.

Add the canonical releng pieces:
- airootfs/etc/mkinitcpio.conf.d/archiso.conf (HOOKS incl. archiso)
- airootfs/etc/mkinitcpio.d/linux.preset (builds initramfs-linux.img)
- mkinitcpio{,-archiso,-nfs-utils} in packages.x86_64

# Live-ISO boot (archiso bootmodes: bios.syslinux + uefi.systemd-boot)
# mkinitcpio-archiso provides the initramfs hooks that find and mount
# airootfs.sfs and switch root into it — without it the live ISO drops
# to emergency mode on boot.
