build-redbear.sh: pre-cook base/redoxfs/userutils to fix installer "Package base not found"

The boot-ABI invalidation ("relink ONLY the static initfs-critical binaries:
base redoxfs userutils bootstrap") rm's each package's repo pkgar + target to
force a relink. Only relibc was in PRECOOK_PKGS, so only relibc got re-published
via the reliable single-recipe `repo cook` path. base/redoxfs/userutils cook
"successful" inside `make live`'s nonstop graph but lose their stage.toml before
publish, so repo marks them outdated and never publishes base.pkgar — the
installer then fails with `Package PackageName("base") not found` at image
assembly (mk/disk.mk).

Add base/redoxfs/userutils to the pre-cook set (both configs, ordered after
relibc which they depend on). The `[ ! -f repo/$pkg.pkgar ]` guard makes it
zero-cost when they were not invalidated. bootstrap is omitted (part of the
base recipe, not a standalone package).
