fix: install init-logind provider before base in buildiso make_rootfs

Same fix as basestrap/main.py: when base depends on init-logind
virtual, pacman --noconfirm picks the first provider alphabetically
(elogind-dinit < elogind-openrc), pulling in dinit -> dinit-rc which
conflicts with openrc (both provide/conflict with init-rc).

Install elogind- as a separate basestrap call BEFORE the
full package list to satisfy init-logind before base needs it.
