fix: use --ignore instead of separate provider call to prevent init conflict

Using --ignore=elogind-dinit (and alphabetically-before providers for
other inits) prevents pacman --noconfirm from resolving init-logind
to the wrong provider. This is more robust than installing the
provider separately, which can fail if base's deps are missing.
