fix(installer): refresh package databases before pacstrap

A ZFS-root install from an aged ISO died in install_base: dkms couldn't build zfs/2.3.3 against a current linux-lts. The ISO bakes the archzfs sync db at build time, so as the ISO ages that db keeps pinning an older zfs-dkms while linux-lts is pulled current from the live mirror. The DKMS module then fails to compile against the newer kernel.

Run pacman -Syy after the archzfs and baked-AUR repos are added to the live pacman.conf and before pacstrap -K, so pacstrap resolves the current zfs-dkms instead of the stale baked one. A plain -y can be skipped by pacman's freshness check against the GitHub-served archzfs db (no reliable timestamps), so -yy forces the refresh.
