Initialise the pacman keyring during install

Browse source 
Fresh installs couldn't update — the live medium's /etc/pacman.d/gnupg doesn't
reliably carry to the target, so the first `pacman -Syu` failed with "keyring is
not writable / required key missing from keyring". Run pacman-key --init +
--populate archlinux in post-install so signature verification works out of the
box. ([breadway] is SigLevel=Never, so no extra key needed.)
